That distinguished scholar and epigraphist, De Rossi, has passed through the crucible of his critical examination all the extant inscriptions of the first six centuries found in the neighbourhood of Rome. In the first volume of his Inscriptiones Christianæ he gives all those with consular dates, thirteen hundred and seventy-four in number. He designs giving in future volumes the remainder of the series, classified according to their doctrinal, historical, or other characteristics. He treats the subject with the utmost candour and moderation, and illustrates these frequently obscure topics with exhaustive and various scholarship. There are now over eleven thousand of these epitaphs extant, which number is being continually increased by the progressive exploration of the Catacombs. From an analysis of their general characteristics and appearance the following results are derived.

The inscriptions are generally engraved on marble slabs from one to three feet long and one foot high, which are used to close the graves of the dead; many, however, are mere scratches on the soft surface of

the plaster, hardened in drying; and some are written with red or black paint, or, more rarely, with charcoal. The letters vary from half an inch to four inches in height, and the incised surface is frequently coloured with a reddish pigment. Prudentius, alluding to this practice of chiseling the letters in stone, calls upon the faithful to “wash with their tears the furrows of those marble slabs.”[672]

The epitaphs are for the most part written in uncial characters, frequently without any separation of the words,[673] although sometimes they are divided by spaces, points, or leaves. They frequently abound also in contractions and monogrammatic abbreviations, imposed by limit of space or economy of labour, as in the following figure:

Fig. 122.—“Gemella sleeps in peace.”

Although sometimes well cut, the inscriptions are often wretchedly executed, presenting a straggling and scarce legible scrawl, as in the following examples, the second of which indicates a transition into the later cursive character.
