(verb) : āmento, āvi, ātum, 1, amentum.
* Lit., to furnish with a strap or thong; esp. of the javelin, to the middle of which a strap was fastened, so that it might be thrown with greater force (very rare; only twice in Cic.): hastae amentatae,Cic. Brut. 78, 271.—Trop., of discourse: amentatae hastae (i. e. apta et parata argumenta),Cic. de Or. 1, 57, 242 (so Juv. sagittae and jaculator, q. v.).—Hence
* Transf., poet., to hurl or dart the javelin by means of a thong: cum jaculum parvā Libysamentavit habenā, * Luc. 6, 221.—And of the wind, which gives an impetus to motion, as a thong to the dart: amentante Noto,Sil. 14, 422.
