Profoundness of mental qualities • depth: I. Lit.: the quality of deepness: 1. altĭtūdo: immense d., infinita, miranda a., Cic.: Caes. 2. prŏfundĭtas (strictly, unfathomable or exceeding d.: rare): Macr. Phr.: sunk to the d. of about 12 feet, circiter duodecim pedes humi depressus, Sall. (but in altitudinem, Cic.): to get out of one's d., vado destitui (cf. Liv. 21, 28, med.); supra plantam evagari, Val. Max. II. Concrete: that which is deep (only in pl.): 1. altum, prŏfundum (the latter poet.): to be drowned in the d.s of the sea, demergi in profundum maris, Vulg.: v. deep. 2. pontus (the deep sea): the d.s of the sea, pontus maris, Virg. A. 10, 377. 3. gurges, ĭtis, m. (strictly, a whirlpool; hence, a deep gulf or abyss): what d.s (of the sea), what streams, qui g., quae flumina, Hor.: Virg.: v. gulf, abyss. 4. fundus (strictly, the bottom of anything): Nereus heaves up the waters from their lowest d.s, imo Nereus ciet aequora fundo, Virg.: v. bottom. Phr.: from the very d.s, imis vadis, Virg. III. The quality of deepness (in other physical applications): (a). measurement from the front: Phr.: 300 feet in d., trecentos (pedes) in agrum, Hor. S. 1, 8, 12: each line was ten men in d., singulae acies denos ordines in latitudinem habuerunt, Front. 2, 3, 22 (where Lipsius conjectured in altitudinem, wrongly: see the place). (b). lowness of pitch in sounds: grăvĭtas: (Kr.): not to have any d. of voice, *graviores voces non assequi; voce exili esse. (c). of hue: austērĭtas: Plin.: or (better), expr. by adj.: color satur, saturior: v. deep. (d). extremity: as in Phr.: it was the d. of winter, erat summa hiems, Cic.: the d. of silence, altum silentium, Sen.: the d. of want, *summa rerum inopia: v. extremity. (e). of forests: perh. expr. by densissimus: as, they hid themselves in the d.s of the forests, *in densissimas silvas se abdiderunt; silvarum profunda, Tac. IV. Profoundness of mental qualities: alta indoles, Liv.: or perh. altitudo mentis (altitudo animi, Cic. Off. 1, 25, 88, is something quite different): cf. Vulg. Rom. xi. 33: O altitudo divitiarum sapientiae et scientiae Dei! (more class., O altam illam ac profundam Dei sapientiam, etc.!): what d. of learning! *quantae doctrinae! quanta rerum abstrusarum ac reconditarum scientia! d. of erudition, intima disciplinae profunditas, Macr. S. S. 7. (Not mentis acies, subtilitas, which denote acuteness or accuracy, rather than depth of mind.)
