The College of Pontiffs was one of the four major priestly colleges; originally their responsibility was limited to supervising both public and private sacrifices, but as time passed their responsibilities increased.[2] The other colleges were the augurs (who read omens), the quindecimviri sacris faciundis (“fifteen men who carry out the rites”), and the Epulones (who set up feasts at festivals).

“The Lex Acilia bestowed power on the college to manage the calendar. Thus, they determined the days which religious and political meetings could be held, when sacrifices could be offered, votes cast, and senatorial decisions brought forth.
The College of Pontiffs came to occupy the Regia (the old palace of the kings) during the early Republican Period. They came to replace the religious authority that was once held by the king. A position, the Rex Sacrorum, was even created to replace the king for purposes of religious ceremonies. “
