This paper takes an energetics-based approach in reexamining the cargo of the famous Marzamemi 2 shipwreck as evidence for the maritime transport of architectural stone and the logistics of religious building projects during Late Antiquity. Drawing on recent discoveries at the site alongside re-assessment of previous finds, it aims to reconstruct the labor investment represented by the partial pre-fabrication of individual components and cargo as a whole, and to contextualize this within a broad understanding of the later ancient stone trade. First, a new inventory of architectural elements and liturgical furnishings from the site is provided. The traces of carving on these elements are then assessed in order to calculate the labor involved in their production. Comparison of this investment to labor costs visible in earlier Roman and contemporary shipwreck cargoes reveals the Marzamemi assemblage as particularly large and ornate-representing perhaps more than 50,000 person-hours-but otherwise typical for the staging of building shipments during the period. These results highlight the significance of the Marzamemi 2 shipwreck within studies of sixth-century CE architectural patronage and trade in decorative stone, while also demonstrating a new application of architectural energetics methodologies to the logistics of complex building programs.

Project 'U Mari examines the long-term relationship between the sea, coast, and local peoples through the various lenses of maritime mobilities, interactions, and livelihoods along the shore of southeast Sicily, specifically between the Vendicari Reserve and Capo Passero. With an eye toward valorizing the 'mattanza' as intangible cultural heritage, our work focuses on the rich material remains of this distinctive Mediterranean form of bluefin tuna trap fishing, using 3D recording and visualization of its associated objects, spaces, and landscapes to relate vivid diachronic stories for the public. Our methodology integrates archaeological survey of the landscape, architecture, and social practices of tuna fishing that act as a bridge between ancient, early modern, and contemporary livelihoods. Through comprehensive digitization, we generate interoperable and parametric models aimed not only at the recording and restoration of objects and spaces, but also-in combination with interviews and archival work-at the valorization and revitalization of traditional practice within contemporary socioeconomic contexts. Through these digital methods, Project 'U Mari seeks to engage the public with a deeper understanding of historical maritime lifeways using exhibition, virtual environments, and revived traditions. Such an approach can encourage environmentally sound fishing practices that draw on local knowledge and yield local economic benefits and responsible tourism. In this way, the historic and archaeological past offers the opportunity to create a new common language for understanding and communicating the architectural evidence of local traditions, history, and livelihoods in this rich maritime landscape.

Leidwanger, J., E.S. Greene and A. Donnelly. "The Sixth-Century CE Shipwreck at Marzamemi." American Journal of Archaeology 125.2: 283-317.

Between 2013 and 2019, collaborative survey and excavation were carried out on the sixth-century CE shipwreck at Marzamemi, in southeast Sicily, originally explored by Gerhard Kapitän in the 1960s. The vessel sank while carrying a primary cargo of nearly 100 tons of extensively prefabricated architectural materials, at least some intended for a church. New finds raise questions about the prevailing narrative of the wreck as em-blematic of a stagnating Late Antique economy, revived only briefly by Justinian. Large but uneven numbers of worked stone elements complicate assumptions regarding their employment as a single set, while additional decorative materials suggest networks of artistry and agency that transcend a single journey. A smaller secondary cargo of am-phoras, along with galley wares and other finds, reveals the extended commercial webs of this merchant vessel and its sailors. Considered together, the assemblage highlights the interdependence and blurring of boundaries between high-end and more mundane exchange. This report offers a new reading of the well-known Late Antique wreck and a more nuanced evaluation of the goods, people, and processes that tied together the Mediterranean during a transformative period toward the end of the Roman empire era. 1

Leidwanger, J. 2020. Roman Seas: A Maritime Archaeology of Eastern Mediterranean Economies. New York: Oxford University Press.

That seafaring was fundamental to Roman prosperity in the eastern Mediterranean is beyond doubt, but a tendency by scholars to focus on the grandest long-distance movements between major cities has obscured the finer and varied contours of maritime interaction. This book offers a nuanced archaeological analysis of maritime economy and connectivity in the Roman east. Drawing together maritime landscape studies and network analysis, Roman Seas takes a bottom-up view of the diverse socioeconomic conditions and seafaring logistics that generated multiple structures and scales of interaction. The material record of shipwrecks and ports along a vital corridor from the southeast Aegean across the northeast Mediterranean provides a case study of regional exchange and communication based on routine sails between simple coastal harbors. Rather than a single well-integrated and persistent Mediterranean network, multiple discrete and evolving regional and interregional systems emerge.
This analysis sheds light on the cadence of economic life along the coast, the development of market institutions, and the regional continuities that underpinned integration-despite imperial fragmentation-between the second century BCE and the seventh century CE. Roman Seas advances a new approach to the synthesis of shipwreck and other maritime archaeological and historical economic data, as well as a path through the stark dichotomies -- either big commercial voyages or small-scale cabotage -- that inform most paradigms of Roman connectivity and trade. The result is a unique perspective on ancient Mediterranean trade, seafaring, cultural interaction, and coastal life.

The contributions to this thematic issue of "HEROM: Journal on Hellenistic and Roman Material Culture" examine the economic development of the Knidian peninsula in southwest Anatolia through the lens of its distinctive transport amphoras. The production, distribution, and consumption of Knidian wine jars shed light on the interplay between external maritime connections and internal networks of settlement and agriculture, offering an opportunity to understand local and regional dynamics within the context of increasing cosmopolitanism of the Hellenistic and Roman eastern Mediterranean.

This volume brings together scholars of Mediterranean archaeology, ancient history, and complexity science to advance theoretical approaches and analytical tools for studying maritime connectivity. For the coast-hugging populations of the ancient Mediterranean, mobility and exchange depended on a distinct environment and technological parameters that created diverse challenges and opportunities, making the modeling of maritime interaction a paramount concern for understanding cultural interaction more generally. Network-inspired metaphors have long been employed in discussions of this interaction, but increasing theoretical sophistication and advances in formal network analysis now offer opportunities to refine and test the dominant paradigm of connectivity. Extending from prehistory into the Byzantine period, the case studies here reveal the potential of such network approaches. Collectively they explore the social, economic, religious, and political structures that guided Mediterranean interaction across maritime space.

In 2007 a symposium was held at Texas A&M University to celebrate the twenty-fifth anniversary of Texas A&M University Press’s publication of the first volume reporting the Yassiada shipwreck site. Seventeen papers from that symposium featured in this book broadly illustrate such varied topics as ships and seafaring life, maritime trade, naval texts, commercial cargoes, and recent developments in the analysis of the Yassiada ship itself.

Clustered along its sinuous shores, the inhabitants of the ancient Mediterranean harnessed the power and potential of the sea to widely varying degrees. For the Roman era, considerable emphasis has been placed on the expansive port networks and large‑scale directed exchange that linked cities across its tamed waters, yet the extent and practical impact of direct maritime access and opportunity beyond urban centers remains a critical question for a population that was still overwhelmingly rural. Using Cyprus as a case study, this paper incorporates GIS‑based analysis of marine and terrestrial topography as a means of exploring the spatial patterning of settlements and activity areas, providing a clearer picture of how simple coastal facilities and easy mobility on and around the island allowed for a distinctively regional scale of maritime economic activity. Centered around what might be considered generally as coastal landing sites, the rise in exchange, fishing, and probably market activities during the Roman (ca. 50 BCE–350 CE) and especially the late Roman (350–700 CE) period suggest that new maritime opportunities counterbalanced the earlier social and economic centrality of the island’s cities, and in doing so restructured the rhythms of rural economic prosperity and connectivity.

Initially explored by pioneering underwater archaeologist Gerhard Kapitän in the 1960s, the famous 6th-c. AD ‘church wreck’ at Marzamemi (Sicily)—with its cargo of prefabricated religious architectural elements—holds a special place in discussions of the ancient stone transport and late antique exchange. Renewed investigations aim to shed light on the broader socioeconomic and historical circumstances surrounding the shipment, including patterns of maritime connectivity between the divergent east and west and the possible roles of imperial agency and local patronage in ambitious architectural programs. Critical to these questions are the origin and destination for the cargo. Stable isotope analysis offers a window into the geographic range of resources available for this architectural program and, by extension, possible clues to the organization of materials, labor, and sponsorship. Analysis of the historical and architectural context allows evaluation of plausible destinations. This study opens new possibilities for interpreting the social and political world of 6th-century exchange and a re-evaluation of the multifaceted relationship between Justinian and the recently acquired imperial lands.

Three-dimensional (3D) models derived from digital survey techniques have increasingly become a mainstay of archaeological research and cultural heritage management. The high accuracy of such modelling makes it an attractive solution for a wide range of challenges from site recording and interpretation to object analysis and reconstruction. The present paper focuses on a new 3D digitization method using stereoscopic video for the documentation, analysis, and representation of archaeological contexts as part of shipwreck investigations off southeast Sicily at Marzamemi. This sixth-century ce vessel sank in shallow water (7–8 m) while carrying a massive cargo of largely prefabricated architectural elements intended for the construction and decoration of a church somewhere in the late antique west. This dynamic site presents significant challenges to the interpretation of depositional and post-depositional events as well the reconstruction of the original cargo and individual architectural elements. Therefore, 3D documentation underwater at Marzamemi has centred on new methods for stereoscopic scanning of the site, topography, and large architectural finds, allowing not only more rapid and precise mapping but insights into site formation processes and the organizational mechanisms behind the cargo assemblage. The adoption of this new system based on a precise workflow and simple, inexpensive hardware combined with readily available software allows more accurate and rapid digital recording underwater to a high standard across scales, from the site level down to the individual artefact. This process, named ISU3D (Integrated System for Underwater 3D Digitization), offers innovative solutions not only for archaeological field research but for heritage management and public outreach.

By combining underwater survey with formal and compositional study of ceramics, recent work at Burgaz (SW Turkey) reveals a late 6th- or 7th-century assemblage of wine and perhaps other agricultural products carried in LR1 and LR2-related amphoras. Representing various southeast Aegean and likely Cilician producers, the mixed cargo aboard this probable shipwreck offers insights into the complex dynamics of seaborne distribution at the end of antiquity. This brief study also underscores the need for documentation in underwater survey of amphora forms and fabrics, particularly those from a period characterized by intensified and diversified production of supra-regional ceramic types.

– 3D models derived from digital survey techniques have increasingly developed and focused on many fields of application, from urban survey and landscapes to individual objects of cultural heritage. The high detailed content and accuracy of such models makes them attractive and useful for a wide range of purposes. The present paper focuses mainly on the combined use of 3D survey techniques of small and medium objects, using the conventional scanner Artec, with ScubaLibre, a 3D stereoscopic scanner system developed by the Suor Orsola Benincasa University team. This paper presents the results obtained during the underwater excavation of a ship that sank near Marzamemi, southeast Sicily, in the 6th century AD. The data collected and processed offers the basis for new analysis of contexts and artifacts found and the development of new forms of musealization of cultural heritage through innovative technologies for augmented reality and immersive environments.

In this one-off, extended Project Gallery article, the participants of a recent workshop jointly present a manifesto for the study of ancient Mediterranean maritime connectivity. Reviewing the advantages and perils of network modelling, they advance conceptual and methodological frameworks for the productive study of seaborne connectivity. They show how progressive research methods can overcome some of the problems encountered when working with uneven datasets spanning large geographical regions and long periods of time. The manifesto suggests research directions that could better inform our interpretations of human connections, both within and beyond the Mediterranean.

Exchange in the Roman Mediterranean has often been described with general network terminology, but rarely have the formal methods or theory of network analysis been applied to the archaeological evidence for Roman maritime interaction. Using case studies around the island of Cyprus, this paper addresses how network approaches might inform analysis of seaborne economic and social connectivity at different scales across the ancient world. The locations of opportunistic ports, and the cargo sizes and approximate durations of journeys represented by shipwrecks provide parameters for characterizing network activity: in this case the networks that linked communities beyond the major coastal urban ports into a highly regionalized maritime economy. This approach to network activity defines and emphasizes a regional scale as distinct from both local and long-distance activity. It raises critical issues about the structure and functioning of networks in light of the socioeconomic conditions and logistics of ancient seafaring, and it provides a framework for investigating the development of markets in the Roman maritime economy. Rather than revealing a single expansive and well-integrated “trade network” across the Roman Mediterranean, the approach here suggests multiple discrete regional and interregional networks centered on distinct products, ships, distances, agents, communities, and economic mechanisms.

Archaeological surveys off Cyprus have brought to light evidence for complex seaborne exchange networks during the Roman era. A shipwreck explored off the island’s southeast coast at Fig Tree Bay offers a profile of a commercial venture that may have been typical of one level of maritime economic integration: a small cargo of primarily Cilician and North Syrian amphoras, along with a handful of more exotic exports. The mixed assemblage hints at broader patterns in the background distribution of agricultural goods between major imperial centers, regional emporia, minor port towns, and outlying non-urban coastal areas. Viewed alongside local maritime activity at two small opportunistic ports, this material record provides a window into the dynamics of seaborne exchange and the intersection of small-scale and short-haul with larger-scale and longer-distance trade. The interplay of these models of exchange bears directly on the role of markets that brought local and international goods and information to a quiet Roman province, and in turn opened Cypriot agricultural produce for consumption across the Roman world. Together, these scattered remains help to fill out a picture of limited maritime economic integration and market development in the northeast Mediterranean and beyond.

The unusually large, well-preserved, and precisely dated amphora assemblage from the early 7th-century Yassıada shipwreck, excavated off the Bodrum Peninsula in Turkey between 1961 and 1964, presents an opportunity to study the dynamics of late Roman ceramic production within the context of large-scale maritime exchange. Detailed typological and metrological studies undertaken since the site’s 1982 publication have demonstrated a wide range of subtypes within each of the two broad amphora groups: the LR1 class and a globular family of amphoras that includes LR2 and other forms. This paper investigates cargo diversity from a complementary archaeometric perspective, namely ceramic petrography, focusing on a limited sample drawn from among the LR1 amphoras. The considerable formal diversity is here mirrored by fabric diversity, with perhaps as many as ten fabrics falling into three discrete groups. Though these fabrics or groups cannot yet be linked with certainty to individual production centers, their mineralogical differences point to origins in a variety of areas that may include Cilicia as well as other regions. Comprehensive analysis holds the potential to shed more light not only on the resources on which the dispatchers of the shipment drew, but also the mechanisms behind agricultural supply of the state and military during the economic and political crises of the early 7th century.

Investigations of Mediterranean connectivity have increasingly turned toward maritime landscape models to frame questions of seaborne exploration, marine resource exploitation, trade and exchange, and seafaring culture. Environmental and technological parameters are consistently acknowledged as crucial for understanding when and why different relationships developed across the sea, but their formal employment in the modeling and interpretation of maritime space remains quite limited. The methodology outlined here utilizes Geographic Information Systems (GIS) to integrate environment and technology as an analytical tool for exploring the complexity of seaborne connectivity. Focusing on sailing days as practical units of distance and using an Archaic Greek shipwreck off Turkey as a case study, this preliminary model demonstrates how a more nuanced spatial approach can inform the human geography and socioeconomic structures of ancient maritime interaction.

Ports served not only as interfaces between land and sea, but as central gathering spaces for economic and cultural exchange. Drawing on case studies from the eastern Mediterranean island of Cyprus, this paper situates opportunistic ports lacking built facilities within a broader socioeconomic context of diverse maritime communications, expanding rural settlement, and increased agricultural productivity during late antiquity. Though simple, these sites served as active agents in the development of new maritime networks as well as local markets throughout their hinterlands, adding flexibility and dynamism to the economic ties between city, countryside, and the wider late Roman world.

Amphoras, the most common ceramic finds in underwater archaeological contexts in the Mediterranean, provide fundamental evidence for the study of seaborne distribution in the ancient economy. This paper opens a brief dialog on the potential complementary contributions of various amphora contexts typically encountered during underwater archaeological survey: not only shipwrecks, but scattered remains at maritime facilities (e.g., harbors and anchorages) and navigational hazards (e.g., promontories and dangerous reefs). Viewed together within a wider setting of material evidence for the ancient economy, the maritime assemblages from these different sites provide comparanda for broad socioeconomic trends evident in the ceramic record on land as well as unique insights into particular distribution mechanisms and seaborne networks. Using Cyprus as a case study, the following discussion draws on patterns observable in the underwater archaeological survey record off the south coast to highlight new details of the island’s regional maritime connections and broader economy, in particular for the Late Roman period (4th to 7th century).

Despite the relative scarcity of early Archaic shipwrecks in the material record of the eastern Mediterranean, three sites off the Turkish coast provide a persuasive argument for an emerging flourish in communication and cultural exchange centering on Cyprus during the 7th century. Comprised largely of Cypriot basket-handle amphoras, often alongside smaller numbers of Aegean jars, these agricultural cargos collectively suggest that direct trade between Cyprus and East Greece played a key role in the expanding economic interaction between the Aegean and the Levant, as well as the emerging internationalism that marked this period more generally.

The recent entry into force of the UNESCO 2001 Convention on the Protection of the Underwater Cultural Heritage raises key legal and ethical issues for the preservation and exploration of shipwrecks, particularly those that lie outside Territorial Seas. With its long history of maritime connectivity and cultural fluidity, and a modern political landscape of national boundaries, the Mediterranean Sea presents a particularly complex scenario. To explore such issues, this paper considers a hypothetical exploration of the ill-fated Napried, a ship used by the 19th-century American consul and antiquarian Luigi Palma di Cesnola to transport his antiquities from Cyprus.

The 2001 UNESCO Convention on the Protection of the Underwater Cultural Heritage came into force on 2 January 2009. As of November 2010, the convention has 35 signatories, of which 10 are states that border the Mediterranean Sea. Because the convention has not been universally adopted by all Mediterranean states, underwater cultural heritage in different areas around the Mediterranean is subject to different claims of ownership and interest. We argue here that maritime archaeologists should play an active role in the stewardship and protection of underwater cultural heritage by working to establish ethical guidelines, best practices, and a clear plan of action for research that falls within, but also outside, current national and international legal protections.

During its annual surveys of the Turkish coast in the 1970s and 1980s, the Institute of Nautical Archaeology discovered two early Archaic (7th- to early-6th-century BC) shipwrecks at Kekova Adası (Antalya region) and Kepçe Burnu (Muğla region); Dokuz Eylül University's Institute of Marine Science and Technology is currently involved in survey of the region. The wrecks, marked by a primary cargo of basket-handle amphoras, indicate exchange between Cyprus and the cities of coastal Asia Minor and Corinth. Such Iron Age internationalism may have been driven by an interest in processed agricultural goods such as olive oil.

New investigations of the famous Marzamemi II ‘church wreck’—originally brought to scholarly and public attention in the 1960s—began in 2013 as part of an overall collaborative initiative combining survey and excavation with heritage management and museum development off the southeast coast of Sicily. Dating around the early 6th-century AD and carrying a monumental cargo of partially prefabricated religious and decorative architectural elements, the shipwreck was almost certainly lost while en route for a building program in the late antique west. Annual fieldwork campaigns over the past four years have shed new light on the major architectural assemblage, while revealing details of additional cargo components, shipboard items, and traces of the hull itself. The following contribution presents results of the 2016 fieldwork and synthesizes new finds with those of earlier reports in this journal (see Leidwanger and Bruno 2014, Leidwanger and Tusa 2015, 2016).

Excavations at Burgaz in southwest Turkey have brought to light a seaside settlement that flourished with maritime activity from the Archaic period through Late Antiquity (ca. 700 BC - AD 650). The home of the ancient Knidians before their move 30 km west to the tip of the Datça peninsula, Burgaz underwent significant transformation in the 4th c. BC, when workshops and industrial zones replaced domestic quarters and public spaces. This shift was concurrent with the expansion of the port city of Knidos as the regional and international center of religious and cultural life. Archaeological explorations of Burgaz’s four harbors since 2011 suggest that in its foundation and initial development, the town served as an entrepôt for communication and agricultural exchange with links around the southeast Aegean. Shifts in the maritime landscape are likewise evident here in the 4th c., when Burgaz’s earliest harbor was left to silt as infrastructure development centered on port facilities a few hundred meters away boasting new agricultural processing installations and ceramic workshops. These contemporaneous developments and the broader reorganization of socioeconomic activity on the peninsula intersect with increasingly international networks of the late Classical and early Hellenistic era. Once at the edge of its maritime region around the Gulf of Hisarönü, Knidos now found itself straddling the much more heavily trafficked lines of communication between the eastern Mediterranean and the Aegean. Tied into these farther-flung networks, it was more desirable as the preeminent cultural and probably also the business hub, even as the best agricultural lands allowed Burgaz to continue flourishing as the peninsula’s economic engine.
Through its evolving fortunes and dynamic maritime landscape—including continued use and expansion of its facilities even as the civic body relocated to Knidos—Burgaz offers a long-term perspective on maritime networks and raises crucial questions about the socioeconomic rationale for the location of port development and shipping routes in antiquity. What social, political, environmental or other motivations are behind the relocation of network hubs, and how do such events unfold with respect to differing positions within Mediterranean connectivity? What drove residents in the fertile center of the Datça peninsula to expand their maritime horizon by capitalizing on rich lands, raw materials, and ceramic production rather than resigning themselves to oblivion once deprived of their earlier civic, religious, and military centrality? How do the technology, design, and utilization of facilities shift with new economic opportunities and broadening maritime horizons? The growing appreciation of harbors as active agents in the construction of multifaceted networks—“nodes of density in the matrix of connectivity” (Horden & Purcell 2000)—offers the chance to look outward at the intersection of one dynamic maritime landscape with broader developments in the connections that set the rhythm of Mediterranean cultural life. The historical, geographical and archaeological setting makes Burgaz one such ideal lens through which to explore Mediterranean connectivity and shifting centers of maritime activity concurrent with regional sociopolitical, economic and technological development, maritime network internationalism, as well as catastrophic and gradual local environmental pressure.

3D models derived from digital survey techniques have increasingly developed and focused on many fields of application, from urban survey and landscapes to individual objects of cultural heritage. The high detailed content and accuracy of such models makes them attractive and useful for a wide range of purposes. The present paper focuses mainly on the combined use of 3D survey techniques of small and medium objects, using the conventional scanner Artec, with ScubaLibre, a 3D stereoscopic scanner system developed by the Suor Orsola Benincasa University team. This paper presents the results obtained during the underwater excavation of a ship that sank near Marzamemi, southeast Sicily, in the 6th century AD. The data collected and processed offers the basis for new analysis of contexts and artifacts found and the development of new forms of musealization of cultural heritage through innovative technologies for augmented reality and immersive environments.

Archaeological investigations at the Archaic through late Roman harbors associated with Burgaz (“Old Knidos”) on Turkey’s Datça peninsula have been conducted since 2011, with the aim of exploring the long-term development of the ports and their integration within the urban settlement. As a collaboration between Brock University, Stanford University and Middle East Technical University, the Burgaz Harbors Project focuses on the changing maritime and economic landscape of the site, before and after the Late Classical expansion of New Knidos at the tip of the peninsula; around this time activity at Burgaz shifts toward large-scale industry. In 2015, fieldwork and analysis focused on research related to the earliest phases of harbor use. Ongoing excavation in Harbor 1 is providing evidence for the development of Burgaz’s initial maritime facility: an enclosed but now largely silted basin adjacent to the city center. The expansion of an excavation area opened in 2014 has revealed well-preserved ceramics and organics. Within the context of these recent finds we explore the relationship between harbor and settlement at Burgaz. As the residents’ needs and the city’s political, social, and economic circumstances changed, so did the urban-harbor matrix. In the settlement’s early stage as a center of regional agricultural activity, a single harbor with minimal architectural embellishment may have served as a multi-functional space. During the Late Classical period, however, Burgaz dedicated significant resources to the construction of a fortified port south of the acropolis, which divided the functional attributes of the harbors between military to the south and communication and commercial activities further north, while retaining physical connectivity to the settlement core. Even after the decline of Burgaz as a primary regional cultural center after the 4th century, the site’s maritime connections appear to expand again, with an emphasis on industrial and commercial activity that shifted focus back toward the north. While investigations in 2015 are revealing clues to the settlement’s early maritime connections, that maritime exchange and investment continues at Hellenistic Burgaz even after its presumed “abandonment” should be no surprise. Evidence from the harbors suggests long term socioeconomic activity along the peninsula in which different small ports and production centers play complementary roles in overlapping local, regional, and interregional maritime networks.

The Marzamemi Maritime Heritage Project is a collaborative excavation, survey, and heritage management initiative focusing on the maritime landscape and seaborne communication off the southeast coast of Sicily. Since 2013, fieldwork here has centered on the famous “church wreck”, which sank while carrying prefabricated architectural elements for the construction of a late antique church—possibly alongside other cargo—from the northern Aegean region during the 6th century. In addition to three field seasons of survey and excavation, efforts have centered on documentation and conservation of previously raised materials, including those excavated in the 1960s by pioneering underwater archaeologist Gerhard Kapitän, as well as complete three-dimensional recording of the dispersed site and individual finds, both in situ and raised. Together, the vessel and its cargo offer insight into the character and patterns of maritime connectivity between the divergent east and west Mediterranean worlds, and the possible complementary roles of imperial agency and local patronage in the ambitious programs of (re-)construction in 6th-century Italy. Equally important to this research, however, is the development of collaborative heritage management and outreach strategies, particularly centered on the development of the new local Museum of the Sea, designed to engage the public and promote responsible cultural tourism in the area.

Initially explored by pioneering underwater archaeologist Gerhard Kapitän in the 1960s, the famous “church wreck” at Marzamemi (Sicily)—with its cargo of prefabricated religious architectural elements—has long held a special place in discussions of the ancient stone transport and late antique exchange more broadly. Building on Kapitän’s work, renewed investigations of the wreck since 2012 have aimed to shed light on the broader socioeconomic and historical circumstances surrounding the shipment. Together, the vessel and its cargo offer insight into the character and patterns of maritime connectivity between the divergent east and west Mediterranean worlds, and the possible roles of imperial agency and local patronage in the ambitious architectural programs across the 6th-century Mediterranean world. Fundamental to answering these and other questions are the identifications of the most likely origin and destination for the cargo. Stable isotope analysis of marble samples collected from the site now offers a window into the geographic range of resources available for such an architectural program and, by extension, clues to the organization of materials, labor, and sponsorship behind such a shipment. Analysis of contemporary churches and other structures that incorporate similar materials along with an examination of corresponding primary textual sources allows for a reassessment of the most plausible destination of this complex cargo. This study, in turn, opens new possibilities for interpreting the social and political world of 6th-century exchange and consumption, including the individuals and institutions involved, and a re-evaluation of the multifaceted relationship between Justinian and the recently acquired imperial lands during his program of renewal.

Roman ports served not only as interfaces between land and sea, but also as central gathering spaces for cultural and economic exchange. With the growing adoption of network metaphors and analytical approaches to maritime connectivity, considerable emphasis has been placed on the centrality and critical “hub” function of major harbors in binding together the far reaches of the Roman world into a vast network. Far less clear, though, is the practical impact of such large-scale structures beyond the major port cities, and how empire-wide links may have interacted with maritime networks operating on local or regional levels. To what extent did seaborne communication and exchange comprise a highly integrated Mediterranean web centered on urban hubs? Can a single network model account not only for this vast geographical area, but for the entire range of products, ships, distances, agents, communities, and economic mechanisms involved? What role might smaller, secondary and opportunistic ports have played in structuring maritime interaction and socioeconomic life in their hinterlands? To what extent were different communities in different localities tied into different maritime networks?
Using Cyprus as a case study, the approach adopted here explores the possible role of maritime networks in daily life, particularly beyond the island’s larger harbor hubs. A GIS-based analysis of maritime and terrestrial topography explores the spatial patterning of settlements and ports, providing a clearer picture of how dense maritime facilities and ease of mobility on and around the island created a low threshold for seaborne connectivity. Rather than relying on the nearest major harbor city, populations outside coastal urban centers enjoyed proximity and easy access to some form of simple port or beach-side anchorage, allowing the sea to play a dynamic role in the forging of links and socioeconomic life more generally across much of the island. The maritime networks that developed were dense but hardly universal or uniform, forming distinct but overlapping scales of regional and interregional activity that reflect the diverse needs of different communities, the complex movements of goods and people, and the varied agents involved.

With four seasons undertaken to date, the Burgaz Harbors Project aims to explore the complex and changing maritime landscape of an Archaic through late Roman port at Burgaz (“Old Knidos”) along the Datça peninsula in southwest Turkey. Through survey onshore and offshore combined with test excavation and geomorphological prospection, this collaborative effort has shed light on the long-term development of Burgaz’s maritime façade, from its initial small but well-built Archaic harbor basin to its elaborately designed and fortified Classical ports, to the simple but massive construction of its Hellenistic and later facility. A comparative view from the city center shows that Burgaz underwent a radical transformation during the late Classical period, when industrial quarters supplanted residential and monumental public structures, probably in association with the relocation of a substantial part of the citizen body and its religious, political, and civic functions to (New) Knidos further west at the tip of the peninsula. Yet built dolia as well as workshop and storage spaces along shore testify to a flourishing industry of wine production well beyond the Classical era. In light of this local socioeconomic history, our investigations explore the life of Burgaz’s four harbors, the original role of the city as a nexus of coastal trade, and the repurposing of port facilities alongside renewed industrial and economic functions.

Ongoing excavation in the city center and harbor complex of Burgaz, on the Datça peninsula in southwest Turkey, provides occasion to investigate the long-term dynamics of ceramic production and maritime circulation from the Archaic era through the end of antiquity. Since 2013, these efforts have included the chemical (pXRF) and mineralogical (petrography) characterization of pottery with an eye toward: (1) identifying the range and variety of local ceramic traditions within Burgaz and its territory, including distinguishing fabric groups representative of smaller production contours across the peninsula; (2) understanding the relationship between changing forms and fabrics over the history of local production based on evidence ranging from excavated workshops to geological prospection in the environs of Burgaz; and (3) quantifying trends in the import and export dynamics of a long-lived eastern Mediterranean maritime center. Since this port town served variously as its own nexus for small-scale, short-haul regional exchange and a link between the local agricultural economy and the wider interregional Mediterranean trade, a detailed analysis of ceramics from the city and harbor contexts may shed light on Burgaz's place in the shifting maritime economics between the Archaic period and late antiquity. This paper presents results of the 2013-2014 analyses, addressing the overall potential of analytical methods here for characterizing the long-term dynamics of maritime economies at the local, regional, and interregional scales.

The Marzamemi Maritime Heritage Project is a multi-period excavation, survey, and heritage management initiative focusing on the maritime landscape and seaborne communication off the southeast coast of Sicily. The concentration of accessible sites and their location at the intersection of the eastern and western Mediterranean facilitates inquiry into long-term structures of regional and interregional maritime exchange throughout antiquity and beyond. The first field seasons (2013-2014) have prioritized exploration and management of the famous Marzamemi “church wreck”, which sank while carrying prefabricated architectural elements for the construction of a late antique church—possibly alongside other cargo—from the northern Aegean region during the 6th century. This fieldwork has focused on documentation and conservation of materials previously raised from the wreck, complete three-dimensional recording of the dispersed site and individual finds, and excavation in several of the more promising sandy areas. Together, the vessel and its cargo offer insight into the character and patterns of maritime connectivity between the divergent east and west Mediterranean worlds, and the possible complementary roles of imperial agency and local patronage in the ambitious programs of (re-)construction in 6th-century Italy. Equally important to this research, however, is the development of heritage management and outreach strategies, including a new museum, designed to engage the public and promote responsible cultural tourism in the area.

Investigations in the harbors of Burgaz (Old Knidos) on Turkey’s Datça Peninsula have been conducted by Brock University and Stanford University since 2011 in tandem with excavation by Middle East Technical University of the Archaic through late Classical habitation site. After the late Classical period, settlement at Burgaz declines and the site is refashioned as an industrial complex. Built dolia and workshop or storage spaces along shore testify to a flourishing industry of wine production. That the town also continues to utilize—and in some places expand—its harbor structures and fortifications into the Hellenistic period, even as the settlement changes its focus toward industry, may suggest that the design of the harbors likewise shifts to meet new needs of local production and distribution. With the growth of Knidos as the region’s preeminent center, looking outward to a larger Hellenistic world, Burgaz does not recede into the economic background. Continued proximity to key resources—fertile agricultural land, raw materials, and ceramic production areas—allow Burgaz to expand its industrial focus on land and at sea, serving as a supplier of products within its immediate region and beyond through integration with the growing maritime economy of Knidos.

Archaeological investigation in the harbors associated with Burgaz or “Old Knidos” on Turkey’s Datça peninsula have been conducted since 2011 in tandem with excavation by Middle East Technical University (METU) of the Archaic through Late Classical habitation site. After the Late Classical period, settlement at Burgaz declines and the site is refashioned as an industrial complex while many of its residents relocate to Knidos at Tekir on the tip of the peninsula. Along the shore and the nearby coastal inland, built dolia and workshop or storage spaces testify to a flourishing industry of wine production. The Burgaz Harbors Project aims to conduct comprehensive survey and excavation in the four harbors associated with the site, seeking answers about the development of the town, its ports, and its integration within a broader maritime cultural and economic landscape.
In 2013 a team from Brock University and Stanford University focused on recording and excavation in and around two of the site’s four harbors: Harbor 1 (L1), believed to be associated with the earliest habitation phases of the site, and Harbor 2 (L2) where built moles and towers may have served a defensive purpose. Limited marine geophysical survey and coring was undertaken for the assessment of chronological phases of the harbor environment with respect to sea level change, as well as environmental reconstruction and the identification of abrupt events. Excavation in the harbors reveals construction built upon piled rubble, designed to create a level surface for the blocks of the moles. Such leveling techniques are not uncommon in harbor construction throughout the eastern Mediterranean, and are also seen on land sites nearby where pebble and rubble foundations served for earthquake protection. Investigations in L2 this year centered not only on archaeology, but also on current and future heritage management in light of increased tourism in the area.

The Marzamemi Maritime Heritage Project is a collaborative excavation, survey, and heritage management initiative focusing on maritime landscape and seaborne communication off the coast of southeast Sicily. The concentration of accessible sites and their location at the intersection of the eastern and western Mediterranean facilitates inquiry into long-term structures of regional and interregional maritime exchange from the early Roman era through Late Antiquity. The first field season in 2013 saw the initiation of new excavations at the site of the Marzamemi II shipwreck, originally discovered and partially explored by Gerhard Kapitän a half-century ago. This vessel appears to have sunk while carrying prefabricated architectural elements for the assembly of a Byzantine church during the 6th century. A rare example of “high trade” in building materials, the ship’s other cargo, personal items, and hull remains could offer unique insight into the relationship between specialized state-driven and independent commerce as well as the ambitious reconstruction program integral to Justinian’s projection of imperial ideology. Alongside archaeological research, the project situates excavation within a broader dialog on natural and cultural heritage practices in the region.

Ports served not only as interfaces between land and sea, but also as central gathering spaces for cultural and economic exchange between mixed communities of farmers, merchants and sailors. The common orientation of coastal Mediterranean populations toward the sea made ports critical for connectivity across the ancient world. While considerable attention has been devoted to the extensive harbor constructions of large cities, many small communities beyond the urban centers were tied into Mediterranean communication through less elaborate and less permanent facilities, often simple open beach landings and anchorages without built infrastructure. How these unassuming spaces functioned, and how people were integrated into larger socioeconomic networks through such ports, remains less clear. What types of merchants used these facilities? How archaeologically visible are such sites, and how might we detect their maritime activities? What opportunities did these ports offer? And how might new spaces of exchange have changed the maritime economic landscape for those living nearby? Drawing on case studies from Cyprus, this paper situates opportunistic ports within a broader socioeconomic context of diverse maritime contacts, expanding rural settlement, and increased agricultural productivity between the Roman and late Roman periods. Though modest and often inconspicuous, these sites served as active agents in the development of maritime networks as well as local markets for residents of associated towns and hinterlands, adding flexibility and dynamism to the economic ties between city, countryside, and the wider world.

Underwater surveys off Cyprus have brought to light a variety of archaeological evidence for seaborne exchange during the Roman era. A shipwreck explored off the island’s southeast coast at Fig Tree Bay offers a profile of a commercial venture that may have been typical of one level of maritime economic integration: a small cargo of primarily Cilician and North Syrian amphoras, along with a handful of more exotic exports. While a single shipwreck can only provide a glimpse into one facet of a wider economic system, the mixed assemblage hints at broader patterns in the background distribution of agricultural goods between major imperial centers, regional emporia, smaller port towns, and outlying non-urban coastal areas. It provides a window into the dynamics of small merchant activity and the intersection of small-scale and short-haul with larger-scale and longer-distance trade. The interplay of these models of exchange bears directly on the role of markets that brought local and international goods and information to a quiet Roman province, and in turn opened Cypriot agricultural produce for consumption across the Roman world. Viewed through this lens, the scattered remains of other shipwrecks and port assemblages along the Cypriot coast help to fill out a picture of limited maritime economic integration and market development in the northeast Mediterranean and beyond.

"Excavations at Burgaz, Turkey conducted by Middle East Technical University (METU) since 1993 have revealed uninterrupted activity from the Geometric period through the early Hellenistic era. At its height in the Archaic and Classical periods, the town’s residents enjoyed extensive domestic quarters and monumental civic structures arranged on an orthogonal plan. With its proximity to some of the most fertile land on the Datça peninsula as well as ready access to the sea, Burgaz is often considered to be the early settlement of the Knidians (Bean and Cook, BSA 47 [1952] 202-204; Bresson, Anatolia Antiqua 19 [2011]: 395). By the late fourth century, the nature of the settlement at Burgaz undergoes a dramatic shift as workshops and industrial zones geared primarily toward processing and storing the region’s agricultural production replace habitation and public spaces. At the same time, Knidos at Tekir on the tip of the Datça peninsula develops as a civic and religious center, well situated at the juncture of the Mediterranean and Aegean seas to take maximum advantage of the growing internationalism of the Hellenistic world.
Ongoing archaeological investigations in the harbor complex of Burgaz have been conducted by Brock University in collaboration with the METU team since 2011. Surface survey and test excavations suggest that in its foundation and initial development, the port served as an entrepôt for communication and trade primarily throughout the Carian region and neighboring islands: an economic zone that may map well onto the Dorian hexapolis described by Herodotus (1.144). That the town continues to utilize—and in some places expand—its harbor structures and fortifications in the Late Classical and Early Hellenistic periods, even as the settlement changes its focus toward industry, may suggest that the design of the harbors likewise shifts to meet the new needs of local production and distribution. With the growth of Knidos as the region’s preeminent religious and economic center, looking outward to a larger Hellenistic world, Burgaz does not recede into the economic background. Rather, the port seems to take on a new role as a link in the supply chain. Continued proximity to the Datça peninsula’s fertile interior, combined with access to raw materials and ceramic production areas at Reşadiye, allows Burgaz to expand its industrial focus on land and at sea, serving as a supplier of agricultural products within its immediate region and beyond through its integration with the growing maritime economy of Knidos."

Exploration of the material remains of Mediterranean ports and harbors extends back to the earliest days of underwater archaeology. Yet such studies have often focused on the strictly technical and architectural at the expense of the social and economic. In addressing together the many facets of these maritime archaeological sites, this session investigates how ports, harbors and anchorages fostered the development of socioeconomic relationships, communities and landscapes across the Mediterranean. Papers in this session will explore, at various analytical scales and through different methodologies, the cultural, environmental and economic processes behind constructed maritime landscapes, the interrelated effects of technological development and socioeconomic change, and the comparative and complementary roles played by a range of diverse facilities from massive built harbors to humble anchorages. Taking up the call of Horden and Purcell (2000, 393) to view these liminal spaces as “nodes of density in the matrix of connectivity”, this session provides a diachronic view of how ports, harbors and anchorages—large and small, built and natural, urban and peripheral, all-weather and seasonal—tied together the coastal populations of the pre-modern Mediterranean.

"The 2001 UNESCO Convention on the Protection of the Underwater Cultural Heritage entered into force on 2 January 2009. The Convention reflects an international response to the looting and destruction of shipwrecks and other submerged sites, and answers the desire by states to assert control over the exploration and exploitation of offshore cultural heritage. At the core of the Convention are four basic principles: (1) an obligation to preserve underwater cultural heritage (UCH); (2) the consideration of in situ preservation of sites as the first option; (3) a prohibition on the commercial exploitation of UCH; and (4) cooperation among states to protect UCH, particularly through training, education and outreach. The Convention includes an Annex outlining rules for research on and sound treatment of UCH based on the 1996 International Council on Monuments and Sites Charter on the Protection and Management of Underwater Cultural Heritage. The legal framework of the Convention builds on the 1982 United Nations Convention on the Law of the Sea, which establishes the zones where states can exert different laws and influence. As of March 2014, the Convention includes 45 states parties, of which 13 border the Mediterranean Sea. While certain states seem likely to sign the Convention in the near future, political considerations may keep others from ratification for the foreseeable future if not indefinitely. Among the “research states” that are most active in Mediterranean waters, the United States, the United Kingdom, and Canada are not current signatories.
In light of the Convention’s entry into force but the remaining uneven situation regarding UCH research and preservation initiatives, this panel brings together archaeologists, scientists, policy experts, and legal specialists to address threats to UCH in national and international waters and the degree of protection provided by the Convention and other law. Participants will explore the current state of UCH protection and the benefits and limitations of the Convention for the implementation of ‘best practices’ in the management of submerged heritage. Emphasis is placed on UCH management in North America and the Mediterranean region."
