Held annually in Rome on August 21, Consualia was a celebration of the harvest held in honor of Consus. There would have been a sacrifice and offerings of the first fruits, followed by horse racing in the Circus Maximus. The horses and chariots would have been decorated in garland and paraded before the altar of Consus, which was kept underground and exposed only on August 21 and at the preceding celebration of Consualia and the Festival of The Pales.
Consus was the ancient Roman Earth God of granary and was connected with the harvest and Autumn sowing. He had an underground barn and altar at the Circus Maximus, which was only uncovered at his twice-yearly festivals. Consus also had a temple on the Aventine Hill, and his sacrifical offerins consisted of first fruits. Consus was also identified with the Greek God Poseidon and with Neptune, presumably because of his association with horses. HIs symbols include the horse and chariot, cornucopia, all fruits, vegetables and grain. His colors are gold, brown, and rust, and his numerical values are 7 and 21.
