آرمیلوستریوم

In ancient Roman religion, the Armilustrium was a festival in honour of Mars, the god of war, celebrated on October 19. On this day the weapons of the soldiers were ritually purified and stored for winter. The army would be assembled and reviewed in the Circus Maximus, garlanded with flowers. The trumpets (tubae) would be played as part of the purification rites. The Romans gathered with their arms and armour on the Aventine Hill, and held a procession with torches and sacrificial animals. The dancing priests of Mars known as the Salii may also have taken part in the ceremony.
