Roman Festivals consecrated to Mars
Practically the whole month of March was consecrated to Mars, the God of War. The god Mars was also associated with the growth of vegetation. His special festivals (Feriae Marti) in March were of a warlike character: on the 9th of March the priests (Salii) began the ancient custom of carrying his sacred shields (ancilia) round the town from one ordained resting-place to another. The Salii priests wore the full war-dress (trabea and tunica picta ) and performed a sacred dance and song round the city accompanied by war trumpets. On the 19th, Quinquatrus, the sacred shields of Mars were solemnly purified, and on the 23rd March the same ceremony was performed with the war-trumpets. His altar was in the Campus Martius, outside the city-walls and horse races were celebrated in his honor. The races of the war-horse were called Equirria on March 14 and February 27, and the great race was run on the Ides of October.
