First, let me say—though the remark hardly comes here in its proper place, yet, as it may help to dissipate a prejudice, let me anticipate a little and say—that the work in its full magnitude, such as we have been describing it, was the work (to speak roughly) of three centuries of labour. There is evidence that the Catacombs were used as Christian cemeteries even before the end of the first century, and they certainly continued to be so used, more or less, up to the first decade of the fifth. Among the inscriptions found in them is one of the year of our Lord 72; there are others of 107, 110, and so on, down to 410; so that the whole period of their use includes almost a century of the Church’s peace, as well as all the time of her persecution. However, here as elsewhere the difficulty is not about the end of the work, but about its beginning. How was it possible that the Christians in the first and second centuries could have executed any part of the great work we have described? How could they have made a beginning? how carried it on? Was it a work done in violation of the law, and therefore in secret? or was it public and notorious, and such as their Pagan neighbours, enemies though they were, could not legitimately interfere with? The answers to these questions are to be sought in learned volumes of old Roman law, and in hundreds of Latin Pagan inscriptions, which, however, cannot be transferred to these pages. For our present purpose their contents may be thus briefly summarised. It was the common practice of Roman gentlemen and ladies of wealth to make in their wills very minute provisions for their tombs, and for certain rites and ceremonies to be performed at their tombs after death. They ordinarily set apart some portion of a field or garden near the high road, accurately measured off with so many feet of frontage and so many feet into the field behind; and in the middle of this plot they ordered a monument to be erected—often a chamber of considerable dimensions, with an altar of stone or of fine marble in which their bones or ashes should be laid, and benches of the same material, with cushions and all else that was necessary for the convenience of guests, whom they invited to come and partake here of a feast in their memory, both on the anniversary of their death and on several other occasions. The cost of the tomb was often specified in the will, and recorded on the epitaph; and the expenses of the feasts were met partly by contributions from dependants of the deceased who were intended to partake of it, partly by the rent of certain houses or gardens, or by the interest of moneys bequeathed by the deceased himself or by others for this purpose. The execution of this part of the will was commonly intrusted to some one or more faithful freedmen, who had a direct interest in its fulfilment; and heavy fines were inflicted on the heirs in case of neglect.
