FOSSORI. — This is the name given, even by pagans, to the workers engaged in digging burial pits. Hippolytus explains why the fossor is paid his wage and the price of the bricks (Apostolica tradita, 34). The fossori liked to have themselves represented in the cubicula of the underground cemeteries. Six are represented in Callistus.
The cemetery ad duas lauros has no fewer than eight cubicula, in each of which two fossori are represented, either at work, or with the sack and the lamp, or with the lamp and the pickaxe; in addition, there are two isolated fossori. In Domitilla, the cubiculum of the fossor Diogenes, damaged by Boldetti, is well known (Wilpert, Pitture, pl. 180). In the cemetery of the Giordani, a copy was made of the depiction of the fossor trofimus intent on his work above ground (J. Wilpert, Die Katahomboengemälde und ihre alten Kopien, Freiburg im Breisgau 1891, pl. 4, 2). Effigies are also found.

In the second half of the fourth century, the sale of tombs by fossors was frequent; they charged high prices, not without some abuse, for tombs situated near the venerated tombs of the martyrs. Quite a few inscriptions are true titles of ownership, documented by the names of the fossors who sold the tomb and by the corresponding price, which had even been paid in gold. One inscription even recalls the presence of all the fossors (O. Marucchi, Monumenti del Museo Cristiano Pio Lateranense, Milano 1910, tav. 3, n. 26).
