The data used for network analysis in this context primarily comes from Roman stamped bricks, particularly those found in the Tiber Valley, which contain rich, multi-dimensional information such as the names of landowners (domini) and brick makers (officinatores), and details about the property or clay source (figlina) and accompanying figurative devices (signal). From these details, networks are constructed where specific pieces of information or entities become the nodes and their recorded relationships (like co-occurrence on a stamp or shared connections) become the links or edges.
Construction
This dataset was created by manually digitising CIL volume XV.1 by the author as a graduate student. The data is a rough and necessarily incomplete transcription of the information contained in the Corpus Inscriptionum Latinarum XV.1 Instrumentum domesticum, edited by H. Dressel, 1891. It should not be used to identify stamped bricks (one should use instead Steinby's 'Indici complementari ai bolli doliari urbani (CIL XV.1) Acta Instituti Romani Finlandiae 11). Its utility lies in being able to be searched quickly, to narrow down the range of possibilities. I offer it in that spirit. It took author approximately 50 hours to produce.
Corpus Inscriptiom Latinarum. Specifically, the author's "working copy" of the CIL XV.1 'Instrumentum Domesticum' data, which was used for the analysis of relationships between figlinae and signa in brick stamps, is mentioned as being available online.
The article focuses on applying this method to explore two main types of networks: those connecting named individuals involved in the industry (like domini linked by shared officinatores) and those connecting stamp elements (figlinae linked by common signa), providing new ways to understand the organisation and logistics of brick production.
