Janus - Rites

Rites

The rites concerning Janus were numerous. Owing to the versatile and far reaching character of the basic function of the god, marking beginnings and transitions, his presence was ubiquitous and fragmented. Apart from the rites solemnizing the beginning of the new year and of every month, there were the special times of year which marked the beginning and the closing of the military season, in March and October respectively. These included the rite of the arma movere on March 1 and that of the arma condere at the end of the month performed by the Salii, and the Tigillum Sororium on October 1. Janus Quirinus was closely associated with the anniversaries of the dedications of the temples of Mars on June 1 (a date that corresponded with the festival of Carna, a deity associated with Janus: see below) and of that of Quirinus on June 29 (which was the last day of the month in the pre-Julian calendar). These important rites are discussed in detail below.

Any rite or religious act whatever first required the invocation of Janus, with a corresponding invocation to Vesta at the end (Janus primus and Vesta extrema). Instances are to be found in the Carmen Saliare, the formula of the devotio, the lutration of the fields and the sacrifice of the porca praecidanea, the Acta of the Arval Brethren.

Although Janus had no flamen, he was closely associated with the rex sacrorum who performed his sacrifices and took part in most of his rites: the rex was the first in the ordo sacerdotum hierarchy of priests. The flamen of Portunus performed the ritual greasing of the spear of the god Quirinus on August 17, day of the Portunalia, on the same date that the temple of Janus in the Forum Holitorium had been consecrated (by consul Caius Duilius in 260 BC). Portunus seems to be a god closely related to Janus, if with a specifically restricted area of competence, in that he presides over doorways and harbours and shares with Janus his two symbols, the key and the stick.
