"It is certainly one of the most ancient and remarkable Christian monuments yet discovered. Its position, close to the highway; its front of fine brickwork, with a cornice of terra-cotta, with the usual space for an inscription (which has now, alas, perished); the spaciousness of its gallery, with its four or five separate niches prepared for as many sarcophagi; the fine stucco on the wall; the eminently classical character of its decorations; all these things make it perfectly clear that it was the monument of a Christian family of distinction, excavated at great cost, and without the slightest attempt at concealment. In passing from the vestibule into the catacomb, we recognise the transition from the use of the sarcophagus to that of the common _loculus_; for the first two or three graves on either side, though really mere shelves in the wall, are so disguised by painting on the outside as to present to passers-by the complete outward appearance of a sarcophagus. Some few of these graves are marked with the names of the dead, written in black on the largest tiles, and the inscriptions on the other graves are all of the simplest and oldest form. Lastly, the whole of the vaulted roof is covered with the most exquisitely graceful designs, of branches of the vine (with birds and winged genii among them) trailing with all the freedom of nature over the whole walls, not fearing any interruption by graves, nor confined by any of those lines of geometrical symmetry which characterise similar productions in the next century. Traces also of landscapes may be seen here and there, which are of rare occurrence in the catacombs, though they may be seen in the chambers assigned by De Rossi to SS. Nereus and Achilles. The Good Shepherd, an _agape_, or the heavenly feast, a man fishing, and Daniel in the lions' den, are the chief historical or allegorical representations of Christian mysteries which are painted here. Unfortunately they have been almost destroyed by persons attempting to detach them from the wall."--_Roma Sotterranea_, p. 70. * * * * * A road to the left now leads to the Via Appia Nuova, passing about a quarter of a mile hence, a turn on the left to the ruin generally known as the _Temple of Bacchus_, from an altar dedicated to Bacchus which was found there, but considered by modern antiquaries as a temple of Ceres and Proserpine. This building has been comparatively saved from the destruction which has befallen its neighbours by having been consecrated as a church in A.D. 820 by Pope Pascal I., in honour of his sainted predecessor Urban I., A.D. 226--whose pontificate was chiefly passed in refuge in the neighbouring Catacomb of St. Calixtus--because of a belief that he was wont to resort hither.
