"Maintenant les murailles sont nues, sauf quelques fragments de chapiteaux oubliés par la destruction; mais elles conservent ce que seules des mains de géant pourraient leur ôter, leur masse écrasante, la grandeur de leurs aspects, la sublimité de leurs ruines. On ne regrette rien quand on contemple ces énormes et pittoresque débris, baignés à midi par une ardente lumière ou se remplissant d'ombres à la tombée de la nuit, s'élançant, à une immense hauteur vers un ciel éblouissant, ou se dressant, mornes et mélancoliques, sous un ciel grisâtre,--ou bien, lorsque, montant sur la plate-forme inégale, crevassée, couverte d'arbustes et tapissée de gazon, on voit, comme du haut d'une colline, d'un côté se dérouler la campagne romaine et le merveilleux horizon de montagnes qui la termine, de l'autre apparaître, ainsi qu'une montagne de plus, le dôme de Saint-Pierre, la seule des œuvres d'homme qui ait quelque chose de la grandeur des œuvres de Dieu."--_Ampère, Emp._ ii. 286. The name of the lane which leads to the baths (_Via all' Antoniana_) recalls the fact that, "with a vanity which seems like mockery, Caracalla dared to bear the name of Antoninus," which was always dear to the Roman people. Passing under the wall of the government-garden for raising shrubs for the public walks, a door on the left of the Via Appia, with a sculptured marble frieze above it, is that of Guidi, the antiquity vendor, who has a small museum here of splendid fragments of marble and alabaster for sale. Opposite is the Vigna of Signor Guidi, who has unearthed a splendid mosaic pavement of Tritons riding on dolphins, and who has here also a collection of antique fragments to be disposed of. On the right, is _SS. Nereo ed Achilleo_, a most interesting little church. The tradition runs that St. Peter, going to execution, let drop here one of the bandages of his wounds, and that the spot was marked by the early Christians with an oratory, which bore the name of Fasciola. Nereus and Achilles, eunuchs in the service of Clemens Flavius and Flavia Domitilla (members of the imperial family exiled to Pontia under Diocletian), having suffered martyrdom at Terracina, their bodies were transported here in 524 by John I., when the oratory was enlarged into a church, which was restored under Leo III., in 795. The church was rebuilt in the sixteenth century, by Cardinal Baronius, who took his title from hence. In his work he desired that the ancient basilica character should be carefully carried out, and all the ancient ornaments of the church were preserved and re-erected. His anxiety that his successors should not meddle with or injure these objects of antiquity is shown by, the inscription on a marble slab in the tribune:
