"C'est la tradition d'un âge de paix représenté par le règne paisible de Saturne; avant qu'il y eut une Roma, ville de la force, il y eut une Saturnia, ville de la paix."—Ampère, Hist. Rom. i. 86.
Virgil represents Evander, the mythical king of the Palatine, as exhibiting Saturnia, already in ruins, to Æneas.
"Hæc duo præterea disjectis oppida muris,
Reliquias veterumque vides monumenta virorum.
Hanc Janus pater, hanc Saturnus condidit arcem:
Janiculum huic, illi fuerat Saturnia nomen."
Æn. viii. 356.
When Romulus had fixed his settlement upon the Palatine, he opened an asylum for fugitive slaves upon the then deserted Saturnus, and here, at a sacred oak, he is said to have offered up the spoils of the Cæcinenses, and their king Acron, who had made a war of reprisal upon him, after the rape of their women in the Campus Martius; here also he vowed to build a temple to Jupiter Feretrius, where spoils should always be offered. But in the mean time, the Sabines, under Titius Tatus, besieged and took the hill, having a gate of its fortress (said to have been on the ascent above the spot where the arch of Severus now stands) opened to them by Tarpeia, who gazed with longing upon the golden bracelets of the warriors, and, obtaining a promise to receive that which they wore upon their arms, was crushed by their shields as they entered. Some authorities, however, maintain that she asked and obtained the hand of king Tatius. From this time the hill was completely occupied by the Sabines, and its name became partially merged in that of Mons Tarpeia, which its southern side has always retained. Niebuhr states that it is a popular superstition that the beautiful Tarpeia still sits, sparkling with gold and jewels, enchanted and motionless, in a cave in the centre of the hill.
After the death of Tatius, the Capitoline again fell under the government of Romulus, and his successor, Numa Pompilius, founded here a Temple of Fides Publica, in which the flamens were always to sacrifice with a fillet on their right hands, in sign of fidelity. To Numa also is attributed the worship of the god Terminus, who had a temple here in very early ages.
Under Tarquinius Superbus, B.C. 535, the magnificent Temple of Jupiter Capitolinus, which had been vowed by his father, was built with money taken from the Volscians in war. In digging its foundations, the head of a man was found, still bloody, an omen which was interpreted by an Etruscan augur to portend that Rome would become the head of Italy. In consequence of this, the name of the hill was once more changed, and has ever since been Mons Capitolinus, or Capitolium.
The site of this temple has always been one of the vexed questions of history. At the time it was built, as now, the hill consisted of two peaks, with a level space between them. Niebuhr and Gregorovius place the temple on the south-eastern height, but Canina and other authorities, with more probability, incline to the north-eastern eminence, the present site of Ara-Cœli, because, among many other reasons, the temple faced the south, and also the Forum, which it could not have done upon the south-eastern summit; and also because the citadel is always represented as having been nearer to the Tiber than the temple: for when Herdonius, and the Gauls, arriving by the river, scaled the heights of the Capitol, it was the citadel which barred their path, and in which, in the latter case, Manlius was awakened by the noise of the sacred geese of Juno.
The temple of Jupiter occupied a lofty platform, the summit of the rock being levelled to receive it. Its façade was decorated with three ranges of columns, and its sides by a single colonnade. It was nearly square, being 200 Roman feet in length, and 185 in width.[21] The interior was divided into three cells; the figure of Jupiter occupied that in the centre, Minerva was on his right, and Juno on his left. The figure of Jupiter was the work of an artist of the Volscian city of Fregellæ,[22] and was formed of terra-cotta, painted like the statues which we may still see in the Etruscan museum at the Vatican, and clothed with the tunica palmata, and the toga picta, the costume of victorious generals. In his right hand was a thunder-bolt, and in his left a spear.
"Jupiter angusta vix totus stabat in Æde;
Inque Jovis dextra fictile fulmen erat."
Ovid, Fast. i. 202.
At a later period the statue was formed of gold, but this figure had ceased to exist in the time of Pliny.[23] When Martial wrote, the statues of Jupiter, Juno, and Minerva, were all gilt.
