GENIUS Copy link • GENIUS 1. (demon), genius (a tutelary spirit; ☞ never figuratively for the spirit; e.g., of a language, of a time, where we ought to say proprietas sermonis, ingenium saeculi, etc.): daemonium: divinum illud (deity, spirit, general term). 2. (talents), ingenium (both of the mental talents and of the person who possesses them): maxima indoles et admirabilis (Quint., ; of the mental powers): vir magni or elati ingenii: vir ingenio praestans: magno ingenio praeditus (of the person): an extraordinary and almost superhuman genius, vir singulari et paene divino ingenio: to be no great genius, non maximi esse ingenii. A genius for anything, admirabilis ad aliquid (e.g., ad dicendum) natura. His youthful productions bear marks of great genius, puerilia alicujus opera et maximam indolem ostendunt et admirabilem (Quint., 10, 1, 90).
