I begin by setting forth the few facts and legends which have come down to us on the subject. According to one story the worship of Diana at Nemi was instituted by Orestes, who, after killing Thoas, King of the Tauric Chersonese (the Crimea), fled with his sister to Italy, bringing with him the image of the Tauric Diana hidden in a faggot of sticks. After his death his bones were transported from Aricia to Rome and buried in front of the temple of Saturn, on the Capitoline slope, beside the temple of Concord. The bloody ritual which legend ascribed to the Tauric Diana is familiar to classical readers; it is said that every stranger who landed on the shore was sacrificed on her altar. But transported to Italy, the rite assumed a milder form. Within the sanctuary at Nemi grew a certain tree of which no branch might be broken. Only a runaway slave was allowed to break off, if he could, one of its boughs. Success in the attempt entitled him to fight the priest in single combat, and if he slew him he reigned in his stead with the title of King of the Wood (_Rex Nemorensis_). According to the public opinion of the ancients the fateful branch was that Golden Bough which, at the Sibyl's bidding, Aeneas plucked before he essayed the perilous journey to the world of the dead. The flight of the slave represented, it was said, the flight of Orestes; his combat with the priest was a reminiscence of the human sacrifices once offered to the Tauric Diana. This rule of succession by the sword was observed down to imperial times; for amongst his other freaks Caligula, thinking that the priest of Nemi had held office too long, hired a more stalwart ruffian to slay him; and a Greek traveller, who visited Italy in the age of the Antonines, remarks that down to his time the priesthood was still the prize of victory in a single combat.
