For these reasons, apparently, Statius calls the Arician grove 'profugis regibus aptum,' a sanctuary of exiled princes, Orestes and Hippolytus.[18] From Suetonius we learn that the ghastly priest was styled _Rex Nemorensis,_ King of the Wood, and that the envious Caligula, thinking the priest had held office long enough, set another athlete to kill him.[19] The title of 'king,' borne by a priest, suggests, of course, the sacrificial king at Borne. Also Mr. Frazer adduces African kings of fire and water, credited with miraculous powers over the elements. They kill nobody and nobody kills them. Then we have Jack-in-the-Green = May-Tree = the Spirit of Vegetation = the May _King_ and the _Queen_ of the May. 'These titles,' as Mannhardt observes, 'imply that the spirit incorporate in vegetation is a ruler, whose creative power extends far and wide.' Possibly so. Now, the King of the Wood, the ghastly priest, lived in the grove of Diana, who (among other things) has the attributes of a tree-spirit. 'May not, then, the King of the Wood, in the Arician grove, have been, like the King of the May ... an incarnation of the tree-spirit, or spirit of vegetation?' Given a female tree-spirit, we should rather expect a _Queen_ of the Wood; and we assuredly do not expect a priest of Diana to represent the supreme Aryan god, nay to incarnate him. But this Mr. Frazer thinks probable.[20] Again, 'since the King of the Wood could only be assailed by him who had plucked the golden bough, his life was safe from assault as long as the bough, or the tree on which it grew, remained uninjured.'[21] Here we remark the nimbleness of Mr. Frazer's method. In vol. i. 4 he had said: 'Tradition averred that the fatal branch' (in the grove near Aricia) 'was that golden bough which, at the Sibyl's bidding, Æneas plucked before he assayed the perilous journey to the world of the dead.' But I have tried to show that, according to Servius, this identification of two absolutely distinct boughs, neither similar nor similarly situated, was the conjecture of 'public opinion' in an age divided from Virgil's date by four hundred years. In the space between vol. i. 4 and i. 231 the averment of tradition, as Mr. Frazer calls it, the inference of the curious, as I suppose, to the effect that Virgil's golden branch and the Arician branch were identical, has become matter of fact for Mr. Frazer. 'Since the King of the Wood could only be assailed by him who had plucked the Golden Bough,' he says; with what follows.[22] But who has told us anything about the breaking, by a fugitive slave, near Aricia, of a _golden_ bough? Nobody, as far as I am aware, has mentioned the circumstance. After an interval of four hundred years, the golden bough of Virgil is only brought by Servius into connection with the wood at Aricia, because Servius, and the public opinion of his age, knew about a branch there, and did not know anything about Virgil's branch of gold.
