On this day when the temple of Jupiter Optimus Maximus had traditionally been dedicated by M. Horatius Pulvillus, the first consul of the Republic, Jupiter was honoured on the Capitol. At some time a feast (epulum) was established. This was a joint feast in honor of Jupiter, Juno and Minerva. The college of three epulones was created in 196 BCE to organize such banquets.
All senators attended the epulum Iovis, which began with a sacrifice (perhaps a white heifer). At the banquet itself, images of the three deities presided, dressed for a feast: Jupiter, his face reddened with minium, was placed on a couch (lectulus), while Juno and
Minerva had sellae. Tables with food were laid before them, and music was played. Therefore this was a gathering of all the senate in the visible presence of the supreme divine guardians occurred in the middle of the festivities of the Ludi Romani occurring throughout the city.
During this event, the senior praetor or other occasionally other magistrate drove a nail into the door frame of the temple to register and symbolize the thanks of this year’s senate to the great Capitoline triad and to also to symbolize the link of the magistrates and senate to the authority of Jupiter renewed for another year.
