Beyo... moreI am an Associate Professor in Stanford's Department of Classics and faculty at the Stanford Archaeology Center. Beyond Stanford, I am a Fellow of the Penn Cultural Heritage Center, a Consulting Scholar of the Mediterranean Section at the University of Pennsylvania Museum of Archaeology and Anthropology, and Affiliated Faculty of the Institute of Nautical Archaeology. My work focuses on Mediterranean mobilities, maritime communities, and systems of exchange. Shipwrecks and port sites, especially in southeast Sicily and southwest Turkey, are central to exploring these themes in the field, providing evidence for connections and the long-term dynamics of communities situated amid the economically, socially, and politically changing worlds from the rise of Rome through late antiquity.
Between 2013 and 2019, I led investigations of the early 6th-century “church wreck” at Marzamemi (Sicily), which sank while carrying nearly 100 tons of marble architectural elements. Work continues through underwater survey, 3D analysis, and publication as well as immersive heritage initiatives in the local Museum of the Sea and associated pop-up exhibits and dive trails. Project 'U Mari extends this collaborative field research in southeast Sicily, interrogating the heritage of diverse but co-dependent interactions with and across the sea that have long defined the central Mediterranean and offer a resource for deeper engagement with the past and sustainable future development. Building on survey since 2017, the project’s newest work examines socioeconomic dynamics spanning 2500 years of tuna fishing through maritime landscape archaeology and documentation of fading material culture and traditional knowledge of the mattanza. Our efforts simultaneously foreground heritage activism through community-based archaeology of the spaces, materialities, and memories of contemporary journeys of forced and undocumented migration across the central Mediterranean.
At Stanford, I teach courses and advise students on topics in Hellenistic, Roman, and late antique archaeology, economies and interaction, port networks, ceramic production and exchange, and Greco-Roman architecture and engineering. My lab at the Archaeology Center serves as a fieldwork base and resource for digital modeling (structured light scanning, laser scanning, photogrammetry, GIS, network analysis) and pottery analysis (petrography, pXRF, computational morphological analysis). One of my current projects, a book-length study titled "Fluid Technologies: Standardization, Efficiency, and the Roman Maritime Economy," arises from various threads of this research with students in the field, lab, and museum, analyzing transport amphoras, port infrastructure, and other clues to ancient technologies of distribution.edit

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.

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.

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.

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).

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).

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.

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.

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.

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.

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."
