Jupiter's was in the centre, whence he was poetically called “Media qui sedet aede Deus” meaning the god who sits in the middle temple. The temple of Jupiter Capitolinus, was built because of a vow made by Tarquinius Priscus, in the Sabine war. Only the foundation of the Temple of Jupiter was laid before his death and his nephew, Tarquin the Proud, finished it with the spoils taken from the neighboring nations. The original temple stood on a high ridge stretching over four acres of ground. The front of the Temple of Jupiter was adorned with three rows of pillars, the other sides with two. The ascent from the ground to the entrance of the temple was by a hundred steps. Fabulous gifts and ornaments were donated to the Temple of Jupiter. The Emperor Augustus gave at one time two thousand pounds weight of gold and in jewels and precious stones worth a small fortune. The original Temple of Jupiter temple was first consumed by fire in the Marian war, and then rebuilt by Sylla. This too was demolished in the Vitellian sedition. Emperor Vespasian undertook the building of a third temple, which was burnt about the time of his death. Domitian raised the last and most glorious of all which featured elaborate and expensive gilding. A Christian church now stands on the Capitol over the site of the Temple of Jupiter.
Roman Places of Worship - The Pantheon
The pantheon was built by Marcus Agrippa, son-in-law to Augustus Caesar, and dedicated most probably to all the gods in general, as the name implies. The structure is a hundred and fifty-eight feet high, and about the same breadth. The roof is curiously vaulted, void places being here and there for the greater strength. The rafters were pieces of brass of forty feet in length. There are no windows in the whole edifice, only a round hole at the top of the roof, which serves very well for the admission of light. The walls on the inside are either solid marble or incrusted with marble. The front, on the outside, was covered with brazen plates, gilt, the top with silver plates which are now changed to lead. The gates were brass were of extraordinary work and magnitude. The Pantheon temple is still standing, with little alteration, besides the loss of the old ornaments and was converted into a Christian church by Pope Boniface III.
Roman Places of Worship - The Temples of Saturn and Janus
There are two other temples, particularly worth notice in Rome, not so much for the magnificence of the structure, as for the customs that depend upon them, and the remarkable use to which they were put. These are the temples of Saturn and Janus. The first was famous on account of serving for the public treasury, the reason being because it was believed that Saturn first taught the Italians to coin money. However, it was most probably because it was the strongest place in the city. All the public registers and records were kept in the Temple of Saturn, among which were the libri elephantini, or great ivory tables, containing a list of all the tribes and the schemes of the public accounts. The Temple of Janus was a square building, some say of entire brass, so large as to contain a statue of Janus, five feet high, with brazen gates on each side, which were kept open in war, and shut in time of peace.
