Understanding Roman table ware distributions in the Mediterranean
an exploratory and confirmatory network analysis of the ICRATES database

Space VS topology

● To what extent can the relationships between table ware sherds inform us of processes that led to their distribution as we know it?
● How can topological and geographical networks complement each other in understanding such processes?
ICRATES
The ICRATES database of table wares from the Roman East(Prof. Jeroen Poblome, Katholieke Universiteit Leuven)
Nearly 30,000 sherds
Identifying meaningful relationships
Understand the complexity of this archaeological dataset
Explore the nature of the economic information stored in the relationships between ceramic data
Understand the dynamics between physical and relational space
→ Relational network of co-presence, representing pottery distribution patterns
→ Geographical network of distance, representing a hypothesis of shortest-distance trade routes

“Roman table ware vessels were transported during every part of their life
cycle over trade routes chosen to minimise travel distance”

ConclusionTopological/exploratory● Highlights large and small patterns● Processes in the ancient past and academic processes● Visualisation and analysis
Geographical/confirmatory● Visualise geographical network● Structure of hypothesis
Space VS topology● Validate hypothesis● Identifies non-spatial structure
