I'm presenting next week at the Society for American Archaeology Annual Meeting. I'm giving two papers. One argues for parsimonious models when we do agent based modeling. The other reverses the f...
Roman epigraphy easily lends itself to network analysis. Stamped brick for instance lets one string together, like pearls, individual landowners, estate names, individual brick makers, signa, brick fabrics, and locations. This leads to very complicated, multi-dimensional networks.
When I first started working with this material, I reduced this complexity by looking only at the humans, whom I tied together based on appearing in the same stamp type together. I called these ‘producer’ networks. I then looked at the ties implied by the shared use of fabrics, or the co-location of brick stamp types at various findspots, and called these ‘manufacturing’ networks.
I then sliced these networks up by reigning dynasty, and developed a story to account for their changing shapes over time.
This was in the late 1990s, and in terms of network theorists I had largely only Granovetter, Hanneman & Riddle, and Strogatz & Watts to go on. The story I told was little more than a just-so story, like how the Camel got its Hump.
I had the shape, I had points where I could hang the story, but I couldn’t account for how I got from the shape of the network in the Julio-Claudian period, to that of the Flavian, to that of the Antonines.
In this talk today, I want to reverse the direction of my inquiry. We are all agreed that we can find networks in our archaeological materials. The problem, I think, for us, is to explain the network processes that produce these patterns, and then to use our understanding of those processes to narrow down the possible entangled human & thing interactions that could give rise to these possible processes.
We need to be able to understand the possible behaviour-spaces that could produce the networks we see, to tease out the inevitable from the contingent. We need to be able to rigorously explore the emergent or unintended consequences of the stories we tell. The only way I know how to do that systematically, is to encode those stories as computer code, to turn them from normal, archaeological storytelling rhetoric, to computational procedural rhetoric.
