This tradition indeed speaks for the great age of the sanctuary, since it seems to date its foundation sometime before 495 B.C., the year in which Pometia was sacked by the Romans and disappears from history. But we cannot suppose that so barbarous a rule as that of the Arician priesthood was deliberately instituted by a league of civilised communities, such as the Latin cities undoubtedly were. It must have been handed down from a time beyond the memory of man, when Italy was still in a far ruder state than any known to us in the historical period. The credit of the tradition is rather shaken than confirmed by another story which ascribes the foundation of the sanctuary to a certain Manius Egerius, who gave rise to the saying, “There are many Manii at Aricia.” This proverb some explained by alleging that Manius Egerius was the ancestor of a long and distinguished line, whereas others thought it meant that there were many ugly and deformed people at Aricia, and they derived the name Manius from Mania, a bogey or bugbear to frighten children. A Roman satirist uses the name Manius as typical of the beggars who lay in wait for pilgrims on the Arician slopes. These differences of opinion, together with the discrepancy between Manius Egerius of Aricia and Egerius Laevius of Tusculum, as well as the resemblance of both names to the mythical Egeria, excite our suspicion. Yet the tradition recorded by Cato seems too circumstantial, and its sponsor too respectable, to allow us to dismiss it as an idle fiction. Rather we may suppose that it refers to some ancient restoration or reconstruction of the sanctuary, which was actually carried out by the confederate states. At any rate it testifies to a belief that the grove had been from early times a common place of worship for many of the oldest cities of the country, if not for the whole Latin confederacy.
§ 2. Artemis and Hippolytus. — I have said that the Arician legends of Orestes and Hippolytus, though worthless as history, have a certain value in so far as they may help us to understand the worship at Nemi better by comparing it with the ritual and myths of other sanctuaries. We must ask ourselves. Why did the author of these legends pitch upon Orestes and Hippolytus in order to explain Virbius and the King of the Wood? In regard to Orestes, the answer is obvious. He and the image of the Tauric Diana, which could only be appeased with human blood, were dragged in to render intelligible the murderous rule of succession to the Arician priesthood. In regard to Hippolytus the case is not so plain. The manner of his death suggests readily enough a reason for the exclusion of horses from the grove; but this by itself seems hardly enough to account for the identification. We must try to probe deeper by examining the worship as well as the legend or myth of Hippolytus.
He had a famous sanctuary at his ancestral home of Troezen, situated on that beautiful, almost landlocked bay, where groves of oranges and lemons, with tall cypresses soaring like dark spires above the garden of Hesperides, now clothe the strip of fertile shore at the foot of the rugged mountains. Across the blue water of the
