Serv. _Aen._ 10. 316 ‘Omnes qui secto matris ventre procreantur, ideo sunt Apollini consecrati, quia deus medicinae est, per quam lucem sortiuntur. Unde Aesculapius eius fingitur filius: ita enim eum [esse] procreatum supra (7. 761) diximus. Caesarum etiam familia ideo sacra retinebat Apollinis, quia qui primus de eorum familia fuit, exsecto matris ventre natus est. Unde etiam Caesar dictus est.’ Footnote 763: A concise account by Roscher, _Lex._ s. v. Apollo 448; Boissier, _Religion Romaine_, i. 96 foll.; Gardthausen, _Augustus_, vol. ii, p. 873. For the _ludi saeculares_ see especially Mommsen’s edition of the great but mutilated inscription recently discovered in the Campus Martius (_Eph. Epigr._ viii. 1 foll.); Diels, _Sibyllin. Blätter_, p. 109 foll.; and the _Carmen Saeculare_ of Horace, with the commentaries of Orelli and Wickham. Footnote 764: _L. L._ 6. 18 fin. and 19 init. Footnote 765: Festus, 119. s. v. Lucaria. Footnote 766: The battle of the Allia was fought on the 18th, the day before the first Lucaria. This no doubt suggested the legend connecting the two, especially as the Via Salaria, near which was the grove of the festival, crossed the battle-field some ten miles north of Rome. Footnote 767: See Friedländer in Marq. 487; Plutarch, _Q. R._ 88. Footnote 768: Mommsen in _Ephemeris Epigraphica_, ii. 205. Footnote 769: i. III; Liv. 24. 3; Cato, ap. Priscian, 629. Much useful matter bearing on _luci_ as used for boundaries, _asyla_, markets, &c., will be found in Rudorff, _Gromatici Veteres_, ii. 260. Footnote 770: ‘Light’ is not uncommon in England for a ‘ride’ or clearing in a wood. Footnote 771: Below, pp. 222, and 228. Footnote 772: On the whole subject of the religious ideas arising from the first cultivation of land in a wild district I know nothing more instructive than Robertson Smith’s remarks in _Religion of the Semites_, Lecture iii.; I have often thought that they throw some light on the origin of Mars and kindred numina. The most ancient settlements in central Italy are now found to be on the tops of hills, probably once forest-clad (see Von Duhn’s paper on recent excavations, _Journal of Hellenic Studies_, 1896, p. 125). For a curious survival of the feeling about woods and hill-tops in Bengal, see Crooke, _Religion, &c., in India_, ii. 87. Footnote 773: _R. R._ 139. For _piacula_ of this kind see also Henzen, _Acta Fratr. Arv._ 136 foll.; Marq. 456. Footnote 774: See below, p. 312. Footnote 775: See a passage in Frontinus (_Grom. Vet._ 1. 56: cp. 2. 263).

Neptunus, 202) compares the σκιάδες of the Spartan Carneia (also in the heat of summer), described in Athenaeus, 4. 141 F. Footnote 778:
