During the latter part of the fourth and the beginning of the fifth century the management of the Catacombs seems to have been no longer in the hands of the ecclesiastical authorities, but under the control of the fossors,[226] with whom the bargain for interment was made by the friends of the deceased. Numerous inscriptions occur in which this bargain is recorded, together with the names of the buyers and sellers, and sometimes those of the witnesses to the contract, and even the price that was paid, as in the following examples: COSTAT NOS EMISSE IANVARIVM ET BRITIAM LOCVM ANTE DOMNA EMERITA A FOSSORIBVS BVRDONE ET MICINMO ET MVSCO RATIONE AVRI SOLIDVM VN SEMES (_sic_)--“It is unquestionable that we, Januarius and Britia, bought a place in front of [the tomb of] Lady Emerita[227] from the fossors Burdo, Micinus, and Muscus, for the consideration of one solidus and a half of gold”--(about $7.) EMPTVM LOCVM A BARTIMISTVM VISOMVM HOC EST ET PRETIVM DATVM A FOSSORE HILARO ID EST FOLN ... PRESENTIA SEVERI FOSS. ET LAVRENT--“The place bought by Bartimistus, that is, a bisomus; and the price paid to the fossor Hilarus, 1400 folles, (about $5 65,) in the presence of the fossors Severus and Laurence.” The fossors also probably prepared and engraved the funeral slabs, as seems to be implied in the following: LOCV MARMARORI 133 (_sic_) QVODRISOMVM--“A quadruple tomb [bought] of the stonecutter.”[228] In the following illustration from the Catacomb of Callixtus the fossor is seen standing in a _cubiculum_ lined with graves, and surrounded by the implements of his labour. On his shoulder is the mattock with which he dug the friable tufa, and in his hand the lamp with the spike by which it was fastened to the rock while he worked. At his feet lie the compasses for marking out the _loculi_, and over his head we read the simple epitaph, “Diogenes the fossor, buried 134 in peace on the eighth before the calends of October.” [Illustration: Fig. 23.--Diogenes the Fossor.] The accompanying engraving from Aringhi shows the fossor actively engaged in excavating the vaulted gallery by the light of the lamp suspended near him. The marks made by the mattocks, in the manner here shown, may be seen in the walls of the passages as plainly as though the fossor had but just ceased his labours.
