Rex Nemorensis

Ruins by the shores of Lake Nemi, in an 1831 engraving


The rex Nemorensis (Latin, "king of Nemi") was a priest of the goddess Diana at Aricia in Italy, by the shores of Lake Nemi, where she was known as Diana Nemorensis.

The priest was king of the sacred grove by the lake. No one was to break off any branch of a certain sacred oak, except that if a runaway slave did so, he could engage the Rex Nemorensis in mortal combat. If the slave prevailed, he became the next king for as long as he could, in turn, defeat challengers.[1][2][3]

The priesthood played a major role in the mythography of James George Frazer in The Golden Bough; his interpretation has exerted a lasting influence.
