divided into two equal parts, halved
Since the Aug. per., esp. in poets, also with other substantives, instead of dimidiatus (v. dimidio), divided into two equal parts, halved: mullus (opp. lupus totus), Mart. 2, 37, 4: crus, Juv. 13, 95: vultus, id. 15, 57: Memnone, id. 15, 5: forma circuli, Plin. 2, 59, 60, § 150: clepsydrae, id. Ep. 6, 2, 5: labro basia dare, i. e. slightly, Mart. 2, 10 and 22; so of busts: Priapus, Mart. 11, 18; cf. Cicero's pun on the half-length likeness of his brother Quintus: frater meus dimidius major est quam totus, in Macr. S. 2, 3 (the word dimidius, for dimidiatus, belongs prob. to Macr. himself).—
figuratively
Trop., so of persons of mixed descent: dimidius patrum, dimidius plebis, half patrician and half plebeian, Liv. 4, 2, 6. —Hence, subst.
the half

quam
Like a comp. with quam: vix dimidium militum quam quod acceperat successori tradidit, Liv. 35, 1, 2; 45, 18, 7.—Prov.: dimidium facti, qui coepit, habet, well begun is half done, Hor. Ep. 1, 2, 40; cf. Aus. Ep. 81.—
the half
Rarely dī-midia, ae, f. (sc. pars), the half: verbenaca decocta in aqua ad dimidias, Plin. 26, 12, 73, § 120.
