. ( Apollon. ap. Sch. Od. l. c. comparesκορυθάϊξ-ῑκοςand explains it as 'shaking the hair of their crests'; others rendered itτρίλοφοι,and othersὀρχησταί: more prob. Hesiod is right as to the sense; the first part isτρίχα(Adv.), the second notἑκάς(as Hes. seems to suggest) butϝῐκ- =Skt.viś-'village', cogn. withϝοῖκος;orϝεικ-,another grade of the same root.)
