Why had the priest to be a runaway slave? Mr. Frazer says: 'He had to be a runaway slave in memory of the flight of Orestes, the traditional founder of the worship....'[38] But the _Greek_ story of Orestes, and its _doublette_ as to Hippolytus, are only ætiological myths, fanciful' reasons why,' attached to a _Latin_ usage. Neither Orestes nor Hippolytus was a slave, like the ghastly priest. The story about Orestes, a fugitive, arises out of the custom of Aricia, and does not explain that custom. Mr. Frazer, I presume, admits this, but thinks that the ghastly priest might perhaps, at one time, save himself by being a runaway. But why a slave? If I might guess, I would venture to suggest that the grove near Aricia may have been an asylum for fugitives, as they say that Borne originally was. There are such sanctuaries in Central Australia. Here, fortunately, Mr. Frazer himself supplies me with the very instances which my conjecture craves. He cites Mr. Turner's 'Samoa' for trees which were sanctuaries for fugitives. These useful examples are given, not in 'The Golden Bough,' but in an essay on 'The Origin of Totemism.'[39] 'In Upolu, one of the Samoan islands, a certain god, Vave, had his abode in an old tree, which served as an asylum for murderers and other offenders who had incurred the penalty of death.' I gather from Mr. Turner's 'Nineteen Years in Polynesia' (p. 285) that the death penalty was that of the blood feud. In his 'Samoa,' Mr. Turner writes concerning trees which were sanctuaries: 'If that tree was reached by the criminal, he was safe, and the avenger of blood could pursue no farther, but wait investigation and trial. It is said that the king of a division of Upolu, called Atua, once lived at that spot. After he died the house fell into decay, but the tree was fixed on as representing the departed king, and out of respect for his memory it was made the substitute of a living and royal protector. It was called _o le asi pulu tangata_, 'the asi tree, the refuge of men.' This reminds me of what I once heard from a native of another island. He said that at one time they had been ten years without a king, and so anxious were they to have some protecting substitute that they fixed upon a large O'a tree (_Bischoffia Javanica_), and made it the representative of a king, and an asylum for the thief or the homicide when pursued by the injured in hot haste for vengeance.[40] There seem to have been three sanctuary trees: one inhabited by a god, Vave; one respected in memory of a king; and one doing duty as a kind of figure-head, or representative of a king.
