 This is particularly true of those gods belonging to the archaic religion of the Romans dating back to the era of kings, the so-called "religion of Numa", which was perpetuated or revived over the centuries.Some archaic deities have Italic or Etruscan counterparts, as identified both by ancient sources and by modern scholars.Throughout the Empire, the deities of peoples in the provinces were given new theological interpretations in light of functions or attributes they shared with Roman deities.
