Amiternini, this festival is assigned to Jupiter. Later Roman sources invented a goddess Meditrina, probably to explain the name of the festival. At the Vinalia urbana on April 23, new wine was offered to Jupiter. Large quantities of it were poured into a ditch near the temple of Venus Erycina, which was located on the Capitol. Regifugium and Poplifugium The Regifugium ("King's Flight") on February 24 has often been discussed in connection with the Poplifugia on July 5, a day holy to Jupiter. The Regifugium followed the festival of Iuppiter Terminus (Jupiter of Boundaries) on February 23. Later Roman antiquarians misinterpreted the Regifugium as marking the expulsion of the monarchy, but the "king" of this festival may have been the priest known as the rex sacrorum who ritually enacted the waning and renewal of power associated with the New Year (March 1 in the old Roman calendar). A temporary vacancy of power (construed as a yearly "interregnum") occurred between the Regifugium on February 24 and the New Year on March 1 (when the lunar cycle was thought to coincide again with the solar cycle), and the uncertainty and change during the two winter months were over. Some scholars emphasize the traditional political significance of the day. The Poplifugia ("Routing of Armies"), a day sacred to Jupiter, may similarly mark the second half of the year; before the Julian calendar reform, the months were named numerically, Quintilis (the fifth month) to December (the tenth month). The Poplifugia was a "primitive military ritual" for which the adult male population assembled for purification rites, after which they ritually dispelled foreign invaders from Rome. Epula Iovis There were two festivals called epulum Iovis ("Feast of Jove"). One was held on September 13, the anniversary of the foundation of Jupiter's Capitoline temple. The other (and probably older) festival was part of the Plebeian Games (Ludi Plebei), and was held on November 13. In the 3rd century BC, the epulum Iovis became similar to a lectisternium. Ludi The most ancient Roman games followed after one day (considered a dies ater, or "black day", i. e. a day which was traditionally considered unfortunate even though it was not nefas, see also article Glossary of ancient Roman religion) the two Epula Iovis of September and November. The games of September were named Ludi Magni; originally they were not held every year, but later became the annual Ludi Romani
