aurīga

1. Frenum (from φράξαι?) is the bridle with which the rider breaks the wild horse, like χαλινός; whereas habena (from hebes, χαβός, κάμψαι,) the rein with which he turns the obedient horse, like ἡνίον. Hor. Ep. i. 15, 13. Læva stomachosus habena dicet eques; sed equi frenato est auris in ore; that is, he minds not the reins, and must feel the bit. Cic. Orat. i. 53. Senatum servire populo, cui populus ipse moderandi et regendi sui potestatem quasi quasdam habenas tradidisset: comp. with Tac. Dial. 38. Pompeius adstrinxit, imposuitque quasi frenos eloquentiæ. 2. Oreæ, aureæ, now only to be found in auriga, were, perhaps, the generic term of frenum and habena, like harness. (v. 137.)
