May observances

The rituals of the Argei were archaic religious observances in ancient Rome that took place on March 16 and March 17, and again on May 14 or May 15. By the time of Augustus, the meaning of these rituals had become obscure even to those who practiced them. For the May rites, a procession of pontiffs, Vestals, and praetors made its way around a circuit of 27 stations (sacella or sacraria), where at each they retrieved a figure fashioned into human form from rush, reed, and straw, resembling men tied hand and foot. After all the stations were visited, the procession, accompanied by the Flaminica
