One of the first families that really piqued my interest in regards to the existence of networks in Pompeii and how they work is the gens Calventia. Part of the reason for this is confusion over how many separate individuals might have bore the name Gaius Calventius Quietus. Unlike the multi-generational occurrences of Gaius Cuspius Pansa, the evidence for the Calventii is considerably more confusing, and fragmentary. There is one example of a monumental inscription for the family, found on a tomb outside the Porta di Ercolano. The remainder of the epigraphic evidence is found in dipinti – electoral programmata for what could be the tomb occupant’s son, grandson, and / or adopted son. The fact that the man had an adopted heir actually creates more problems, as that man, known as Gaius Calventius Sittius Magnus, was born into the gens Sittia, which had other members also run for election at roughly the same time. Whose dipiniti is whose is, in some cases, impossible to determine, as is the actual number of people the dipiniti represents. I have made some attempt to tease apart this evidence, and provide some insight into the difficulty one can encounter in dealing with this material in an article that was just published in the Italian journal Athenaeum.
