Apollodorus, i. 9. 7; Virgil, _Aen._ vi. 592 _sqq._; Pliny, _Nat. Hist._ ii. 140, xxviii. 14 (referring to the first book of L. Piso’s _Annals_); Livy, i. 31. 8; Aurelius Victor, _De viris illustribus_, 4; Zonaras, _Annal._ vii. 6. According to another account Tullus Hostilius was murdered by his successor Ancus Martius during a violent storm (Dionysius Halicarnasensis, _Antiquit. Rom._ iii. 35; Zonaras, _l.c._). Footnote 584: Livy, i. 2. 6; Ovid, _Metam._ xiv. 598-608; Pliny, _Nat. Hist._ iii. 56; Dionysius Halicarnasensis, _Antiquit. Rom._ i. 64; Servius on Virgil, _Aen._ i. 259; Aurelius Victor, _Origo gentis Romanae_, 14. Only the last writer mentions the thunderstorm. Footnote 585: Livy, i. 16; Cicero, _De legibus_, i. 1. 3; _id._, _De re publica_, i. 16. 25, ii. 10. 20; Ovid, _Fasti_, ii. 475-512; Plutarch, _Romulus_, 27 _sq._; Dionysius Halicarnasensis, _Antiquit. Rom._ ii. 56 and 63; Zonaras, _Annal._ vii. 4; Aurelius Victor, _De viris illustribus_, 2; Florus, _Epitoma_, i. 1. 16-18. From Cicero (_De legibus_, i. 1. 3) we learn that the apparition of Romulus to Proculus Julius took place near the spot where the house of Atticus afterwards stood, and from Cornelius Nepos (_Atticus_, 13. 2) we know that Atticus had an agreeable villa and shady garden on the Quirinal. As to the temple of Quirinus see also Varro, _De lingua Latina_, v. 51; Festus, pp. 254, 255, ed. C. O. Müller; Pliny, _Nat. Hist._ xv. 120. As to the site of the temple and the question whether it was identical with the temple dedicated by L. Papirius Cursor in 293 B.C. (Livy, x. 46. 7; Pliny, _Nat. Hist._ vii. 213) see O. Richter, _Topographie der Stadt Rom_, 2nd Ed., pp. 286 _sqq._; G. Wissowa, _Gesammelte Abhandlungen_ (Munich, 1904), pp. 144 _sqq._ Footnote 586: See A. B. Cook, “Zeus, Jupiter, and the Oak,” _Classical Review_, xviii. (1904) pp. 368 _sq._; _id._ “The European Sky-god,” _Folk-lore_, xvi. (1905) p. 281. But a serious argument against the proposed derivation of Quirinus from _quercus_ is that, as I am informed by my learned philological friend the Rev. Prof. J. H. Moulton, it is inconsistent with the much more probable derivation of Perkunas from _quercus_. See below, p. 367, note 3. Footnote 587: See above, vol. i. pp. 262 _sqq._ Footnote 588:
