Diana Nemorensis ("Diana of Nemi"), also known as "Diana of the Wood", was an Italic form of the goddess who became Hellenised during the fourth century BC and conflated with Artemis. Her sanctuary is on the northern shore of Lake Nemi beneath the rim of the crater and the modern city Nemi.
The worship of Diana at Nemi was supposedly instituted by Orestes, who fled with his sister Iphigenia to Italy, bringing with him the image of the Tauric Diana hidden in a mound of sticks. After his death, the myth has it, Orestes' 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.
