The dirty lane, with its shabby houses, and grass-grown spaces, and filthy children, has little to remind one of the appearance of the hill as seen by Virgil and Propertius, who speak of the change in their time from an earlier aspect.

"Hinc ad Tarpeiam sedem, et Capitolia ducit,
Aurea nunc, olim, silvestribus horrida dumis,
Jam tum religio pavidos terrebat agrestes
Dira loci; jam tum silvam saxumque tremebant."
Virgil, Æn. viii. 347.

"Hoc quodcumque vides, hospes, qua maxima Roma est,
Ante Phrygem Aeneam collis et herba fuit."
Propertius, iv. eleg. I.

It was on this side that the different attacks were made upon the Capitol. The first was by the Sabine Herdonius at the head of a band of slaves, who scaled the heights and surprised the garrison, in B.C. 460, and from the heights of the citadel proclaimed freedom to all slaves who should join him, with abolition of debts, and defence of the plebs from their oppressors; but his offers were disregarded, and on the fourth day the Capitol was re-taken, and he was slain with nearly all his followers. The second attack was by the Gauls, who, according to the well-known story, climbed the rock near the Porta Carmentale, and had nearly reached the summit unobserved—for the dogs neglected to bark—when the cries of the sacred geese of Juno aroused an officer named Manlius, who rushed to the defence, and hurled over the precipice the first assailant, who dragged down others in his fall, and thus the Capitol was saved. In remembrance of this incident, a goose was annually carried in triumph, and a dog annually crucified upon the Capitol, between the temple of Summanus and that of Youth.[42] This was the same Manlius, the friend of the people, who was afterwards condemned by the patricians on pretext that he wished to make himself king, and thrown from the Tarpeian rock, on the same spot, in sight of the Forum, where Spurius Cassius, an ex-consul, had been thrown down before. To visit the part of the rock from which these executions must have taken place, it is necessary to enter a little garden near the German Hospital, whence there is a beautiful view of the river and the Aventine.

"Quand on veut visiter la roche Tarpéienne, on sonne à une porte de peu d'apparence, sur laquelle sont écrits ces mots: Rocca Tarpeia. Une pauvre femme arrive et vous mène dans un carré de choux. C'est de là qu'on précipita Manlius. Je serais desolé que le carré de choux manquât."—Ampère, Portraits de Rome.

This side of the Intermontium is now generally known as Monte Caprino, a name which Ampère derives from the fact that Vejovis, the Etruscan ideal of Jupiter, was always represented with a goat.[43] On this side of the hill, the viaduct from the Palatine, built by Caligula (who affected to require it to facilitate communication with his friend Jupiter), joined the Capitoline.

We have still to examine the north-eastern height, the site of the most interesting of pagan temples, now occupied by one of the most interesting of Christian churches. The name of the famous Church of Ara-Cœli is generally attributed to an altar erected by Augustus to commemorate the Delphic oracle respecting the coming of our Saviour, which is still recognised in the well-known hymn of the Church:

Teste David cum Sibylla.[44]

The altar bore the inscription "Ara Primogeniti Dei." Those who seek a more humble origin for the church, say that the name merely dates from mediæval times, when it was called "Sta, Maria in Aurocœlio." It originally belonged to the Benedictine Order, but was transferred to the Franciscans by Innocent IV. in 1252, since which time its convent has occupied an important position as the residence of the General of the Minor Franciscans (Grey-friars), and is the centre of religious life in that Order.

The staircase on the left of the Senators' palace, which leads to the side entrance of Ara-Cœli, is in itself full of historical associations. It was at its head that Valerius the consul was killed in the conflict with Herdonius for the possession of the Capitol. It was down the ancient steps on this site that Annius, the envoy of the Latins, fell (B.C. 340), and was nearly killed, after his audacious proposition in the temple of Jupiter, that the Latins and Romans should become one nation, and have a common senate and consuls. Here also,[45] in B.C. 133, Tiberius Gracchus was knocked down with the leg of a chair, and killed in front of the temple of Jupiter.
