some time they rested, but at length were restored to their original
tombs, the one on the Ostian Way, the other on the Vatican. But St.
Peter was again to be laid in this secret chamber in the earth on the
Appian Way. In the episcopate of the saint and scoundrel Callixtus,
the Emperor Elagabalus, with characteristic extravagance and caprice,
resolved to make a circus on the Vatican, wide enough for courses of
chariots drawn by four elephants abreast. All the older buildings in the
way were to be destroyed, to gratify this imperial whim; and Callixtus,
fearing lest the Christian cemetery, and especially the tomb of the
prince of the apostles might be discovered and profaned, removed the
body of St. Peter once more to the Appian Way. Here it lay for forty
years, and round it and near it an underground cemetery was gradually
formed; and it was to this burial-place, first of all, that the name
Catacomb,[B] now used to denote all the underground cemeteries, was
applied.

first instance of its use is in the letter of Gregory from which we
derive the legend. This letter was written A.D. 594.]

Though at length St. Peter was restored to the Vatican, from which he
has never since been removed, and where his grave is now hidden by his
church, the place where he had lain so long was still esteemed sacred.
The story of St. Sebastian relates how, after his martyred body had been
thrown into the Cloaca Maxima, that his friends might not have the last
satisfaction of giving it burial, he appeared in a vision to Lucina, a
Roman lady, told her where his body might be found, and bade her lay it
in a grave near that in which the apostles had rested. This was done,
and less than a century afterward a church rose to mark the place of his
burial, and connected with it, Pope Damasus, the first great restorer
