Argei

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. After all the stations were visited, the procession moved to the Pons Sublicius, the oldest known bridge in Rome, where the gathered figures were tossed into the Tiber River.

Both the figures (effigies or simulacra) and the stations or shrines were called Argei, the etymology of which remains undetermined.

The continuation of these rites into the later historical period when they were no longer understood demonstrates how strongly traditionalist the Romans were in matters of religion.

Interpretations

Before the ritual commenced, an effigy was placed in each of the 27 (or in some sources 24) shrines of the Argei (sacra Argeorum) throughout the Servian regions. The effigies were thought to absorb pollution within the area, and their subsequent sacrifice was a ritual purification of the city. The pontiffs and Vestals were the main celebrants. The exact route of the procession among the stations is unclear.
