The 15th of July was a colourful day in the streets of Rome. In order to celebrate the help received at the battle of Lake Regillus from Castor and Pollux, who watered their horses in the Roman Forum after the victory, a cavalry parade was established for 15 July by the censor Q. Fabius RuUianus in 304 BCE. This was a grand parade of the Roman equestrians who road from the Temple of Mars to the Temple of Castor and Pollux in the forum as if coming from battle, crowned with olive branches and wearing their purple robes with stripes of scarlet known as trabeae.
This was not only a military parade, but it may well have been linked to the census of the Equites which was conducted every five
years by the censors. Participating in this parade was likey a testing of qualification: The censors were probably at the temple of Castor and Pollux in the Forum. There each man then advanced individually to the Censores and was either passed or discharged. If passed they would then each offer an offering to Castor and Pollux and then proceed to the Temple of Jupiter where a ceremony offering another state sacrifice was offered.
While this review by the censors continued throughout the Republic until the censorship fell into disuse in the time of Sulla, but it was revived by Augustus. Forum at the temple of Castor and Pollux and then perhaps passing on up to the temple of Jupiter on the Capitol must have been a brave sight.
