Same entry in Photius, Lexicon kappa449 Theodoridis; cf. Hesychius kappa1711 (with the gloss a(ya/menos).
The verb appears only at 2 Maccabees 14:43 LXX, in this form, the aorist participle active, and with this meaning. The simple verb is also found only once, of finding the range with artillery (Apollodorus of Damascus, Poliorcetica 144.11 Wescher). The adjective eu)/qiktos and its adverb are, however, somewhat commoner, usually of a witticism that hits the mark (epsilon 3498).
The gloss is interesting evidence that this compound of tugxa/nw (tau 1147, epsilon 3344, tau 430) can retain for the lexicographers its original sense of deliberately hitting the mark (eta 286), without the overtones of pure chance (cf. tau 1232, tau 1233, tau 1234) that become more and more important to its meaning in later Greek; cf. epsilon 2738, epsilon 2674, epsilon 2748, epsilon 2673.
