The most important three were the flamines maiores (or "major priests"), who served the three chief Roman gods of the Archaic Triad. The remaining twelve, two of whom are unknown, were the flamines minores ("lesser priests").The fifteen flamines were part of the Pontificial College which administered state sponsored religion in Rome. When the office of flamen was vacant, a pontifex could serve as a temporary replacement, although only the Pontifex Maximus is known to have substituted for the Flamen Dialis.The official costume of a flamen, of great antiquity, was a hat called an apex and a heavy woollen cloak called a laena. The laena was a double-thick wool cloak with a fringed edge, and was worn over the flamen's toga with a clasp holding it around his throat.
