And now at length we must conclude our visit to St. Callixtus. We fear that we have already enumerated more than can be seen with advantage during the course of a single visit; yet it is worth an effort to see it all, because it includes monuments which illustrate nearly every century of the period during which the Catacombs were used. It is for this reason that a visit to St. Callixtus is so singularly valuable, whether it be intended to take this cemetery as a sample of all, or only to use it as an introduction to others. Those who propose to pursue the subject further would do well to visit next the Catacomb of SS. Nereus and Achilles, which lies at no great distance, off the Via Ardeatina; then the Cemetery of Pretextatus on the other side of the Via Appia; and finally, the Cœmeterium Ostrianum on the Via Nomentana. When these have been carefully examined, there will still remain many interesting monuments, of considerable historical importance, in other less famous cemeteries; but enough will have been seen to give an excellent general acquaintance with the main characteristics of Roma Sotterranea.
