Ovid, _Fasti_, i. 607 _sqq._, iv. 953 _sq._ Tiberius refused a similar honour (Suetonius, _Tiberius_, 26); but Domitian seems to have accepted it (Martial, viii. 82. 7). Two statues of Claudius, one in the Vatican, the other in the Lateran Museum, represent the emperor as Jupiter wearing the oak crown (W. Helbig, _Führer durch die öffentlichen Sammlungen klassischer Altertümer in Rom_, 2nd Ed., i. Nos. 312, 673).

οἱ πρὶν γάρ τε Δίας πάντας κάλεον βασιλῆας, οὕνεκά μιν καλὸς Διὸς ἀστὴρ σκῆπτρον ὀπάζει.
τοὺς βασιλεῖς δ’ ἀνέκαθε Δίας ἐκάλουν πάντας.

Virgil, _Aen._ vi. 772. I have to thank Mr. A. B. Cook for directing my attention to the Alban kings and their interesting legends. See his articles “Zeus, Jupiter, and the Oak,” _Classical Review_, xviii. (1904) pp. 363 _sq._; “The European Sky-god,” _Folk-lore_, xvi. (1905) pp. 285 _sqq._

As to the derivation of the name Julus, see Aurelius Victor, _op. cit._ 15, “_Igitur Latini Ascanium ob insignem virtutem non solum Jove ortum crediderunt, sed etiam per diminutionem, declinato paululum nomine, primo Jobum, dein postea Julum appellarant_”; also Steuding, in W. H. Roscher’s _Lexikon d. griech. u. röm. Mythologie_, ii. 574. Compare W. M. Lindsay, _The Latin Language_ (Oxford, 1894), p. 250. According to Diodorus, the priesthood bestowed on Julus was the pontificate; but the name Julus or Little Jupiter suggests that the office was rather that of Flamen Dialis, who was a sort of living embodiment of Jupiter (see below, pp. 191 _sq._), and whose name of _Dialis_ is derived from the same root as Julus. On the Julii and their relation to Vejovis see R. H. Klausen, _Aeneas und die Penaten_, ii. 1059 _sqq._
