In ancient Roman religion, a flamen was a priest assigned to one of fifteen deities with official cults during the Roman Republic. 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 were the flamines minores ("lesser priests"). Two of the minores cultivated deities whose names are now unknown; among the others are deities about whom little is known other than the name. During the Imperial era, the cult of a deified emperor (divus) also had a flamen.
