Builders of the Catacombs

So unending and extensive were the labors of excavating and maintaining the catacombs, it is not surprising that the occupation of grave-digging achieved the dimensions of a career in ancient Rome.  A guild known as fossores, or "diggers," was formed to manage the cemeteries.  The position was a humble one, but by the fourth century, the ranks of this guild included a chief fossor, or mensor, a position combining the skills of an engineer and a master builder, who administered and scheduled the work for each catacomb.  The many benefits and privileges of the fossores grew to such an extent that, around the end of the fourth and beginning of the fifth century, they became property managers an vendors of the tombs.  Their business ventures ceased by the mid-fifth century, however, following abuses of this privilege (1).  The burial grounds used by Jews probably operated in a similar fashion.

In the large grotto of the Monteverde catacomb, Muller found the head of an ascia or pickaxe, one of the most important tools of the fossor.  The head was twenty-five centimeters long and three centimeters wide at its greatest width; in the center of the head was a hole into which a wooden handle must have been inserted.  While this implement figures widely in frescoes and reliefs in the Christian catacombs, only three representations of it have been found in the Jewish catacombs of Rome; on each in the catacombs of Villa Torlonia and Vigna Cimarra, and one carved out of the tuff in the Vigna Randanini catacomb.

Specific groups of fossores seem to have operated in particular areas of the city.  This would account for similarities in ornamentation and styles of lettering of the inscriptions within catacombs.  Epitaphs of purchasers of tombs from the catacombs of San Lorenzo and Commodilla corroborate these connections (2).  In certain cases, however, as in the Torlonia catacombs, different groups of fossores worked at the same time on one site, using their own particular construction methods in in regions or catacombs or adjoining burial grounds (3).
