Populated with 3D block models, the digital elevation model enabled advanced viewshed
analyses that clarify which monuments were visible to—and interacted with—one another. This article demonstrates the capabilities and analytical potential of such modeling by examining the monuments dedicated to and by the Attalid dynasty of Pergamon and how these constructions affected the experience of the city’s built environment.
Lindian Chronicle Connections: Contrasting Rhodian Networks Real and Imagined
Journal of Historical Network Research, 2022

This paper diagrams the network captured by this text, and then seeks to explain why it was invoked by the Lindians at this particular historical moment (100 BCE). This secondary goal is accomplished by considering archaeological and textual evidence for Rhodian trade in the second half of the 2nd c. BCE, and comparing the resulting ‘real’ trade network with the ‘imagined’ network of the inscription. This comparison leads to the conclusion that the network of the Lindian Chronicle was invoked to reassure the local populace of Rhodes’ unshakable historical importance in Mediterranean interstate trade, at a time when that trade – the life blood of the island – had precipitously dropped.
Attalid Networks: Seeking Status And Acquiring Authority Beyond State Capacity
This dissertation examines how the Attalids, despite—even because of—a fairly limited military ca... more This dissertation examines how the Attalids, despite—even because of—a fairly limited military capacity, achieved a status in the eastern Mediterranean comparable to the great powers such as the Ptolemies, Seleucids, or Antigonids. I demonstrate that the Attalids pursued this status as an alternative source of influence to compensate for the limits of traditionally defined military- political power. Methodologically, I use network analysis as a starting point for organizing and visualizing Attalid interstate status signaling, drawing on a wide range of evidentiary sources: epigraphy, archaeology, literature, numismatics, and other material sources. My use of networks is fundamentally descriptive, while my analysis is rooted in modern International Relations theories of status, authority, and hierarchies. The dynasty’s pursuit of status enabled it to have an outsized role within their interstate system and to expand from a single city to a sizable kingdom spanning most of Asia Minor....
