As a city lacking the resources to build its own physical infrastructure, Rome relied on a dense network of distributed places - farms, industrial sites, ports, and roads - for supply. One of these distributed places was the upper part of the Middle Tiber Valley, which supplied Rome with the bricks and tiles that built its imperial fabric. While the area’s brick stamps, produced by local equestrian M. Rutilius Lupus, have attracted perhaps the most scholarly attention, much of the production pipeline, process, and people involved remains obscure. This project aims to examine the labor, economics, and environments of the upper parts of the Middle Tiber Valley through a field survey of tegulae, or Roman roofing tiles. To do so, we surveyed a collection of 61 tegulae sherds found on the surface that had been discarded by local farmers. By recording the dimensions and features of the surveyed tegulae, we gained insight into the local manufacturing process and the lives of the ordinary Roman.
