Quirinus was an ancient Roman deity who closely resembled Mars, the god of war. His name is associated with that of the Quirinal, one of the seven hills on which Rome was built. Eventually, Quirinus was identified with Romulus, one of the legendary founders of Rome, and his festival on February 17 coincided with the date on which Romulus was believed to have been deified. This festival was also associated with the advent of spring warfare, when the shields and weapons of the army, which had been purified and retired for the winter, were brought out. Discuss
