According to Dionysius of Halicarnassus (ii. 48), a Sabine word, and perhaps to be derived from quiris, a lance or spear. It occurs first of all as the name of Romulus, after he had been raised to the rank of a divinity, and the festival celebrated in his honour bore the name of Quirinalia (Virg. Aen. i. 292: Cic. De Nat. Deor. ii. 24; Ov. Am. iii. 8. 51, Fast. iv. 56, 808, vi. 375, Met. xv. 862.) Owing to the probable meaning of the word it is also used as a surname of Mars, Janus, and even of Augustus. (Ov. Fast. ii. 477; Serv. ad Aen. vii. 610; Sueton. Aug. 22 Macrob. Sat. i. 9; Virg. Georg. iii. 27; Lydus, De Mens. p. 144; comp. ROMULUS.)
