The theory that Roman tombs were built along the high roads in two or three rows only, so that they could all be seen by those passing, has been shown by modern excavations to be unfounded. The space allotted for burial purposes was more extensive than that. Sometimes it extended over the whole stretch of land from one high-road to the next. Such is the case with the spaces between the Via Appia and the Via Latina, the Labicana and Prænestina, and the Salaria and Nomentana, each of which contains hundreds of acres densely packed with tombs. In the triangle formed by the Via Appia, the Via Latina, and the walls of Aurelian, one thousand five hundred and fifty-nine tombs have been discovered in modern times, not including the family vault of the Scipios.[124] Nine hundred and ninety-four have been found on the Via Labicana, near the Porta Maggiore, in a space sixty yards long by fifty wide. The number of pagan tombstones registered in volume vi. of the "Corpus" is 28,180, exclusive of the _additamenta_, which will bring the grand total to thirty thousand. As hardly one tombstone out of ten has escaped destruction, we may assume as a certainty that Rome was surrounded by a belt of at least three hundred thousand tombs.

In this respect, the perusal of parts II., III., and IV. of the sixth volume of the "Corpus" is more useful to the student than all the handbooks and "Sittengeschichten" in the world; and besides, the reading is not dry and tiresome, as one might suppose. Many epitaphs give an account of the life of the deceased; of his rank in the army, and the campaigns in which he fought; of the name of the man-of-war to which he belonged, if he had served in the navy; of the branch of trade he was engaged in; the address of his place of business; his success in the equestrian or senatorial career, or in the circus or the theatre; his "état civil," his age, place of birth, and so on. Sometimes tombstones display a remarkable eloquence, and even a sense of humor. Here is an expression of overpowering grief, written on a sarcophagus between the images of a boy and a girl: "O cruel, impious mother that I am: to the memory of my sweetest children. Publilius who lived 13 years 55 days, and Æria Theodora who lived 27 years 12 days. Oh, miserable mother, who hast seen the most cruel end of thy children! If God had been merciful, thou hadst been buried by them." Another woman writes on the urn of her son Marius Exoriens: "The preposterous laws of death have torn him from my arms! As I have the advantage of years, so ought death to have reaped me first."
