[492] See Duchelais’ _Observations_, p. 75; Tochon’s _Dissertation_, pp. 26 and 64; Maffer’s _Museum Veronense_, p. 135; Johanneau in _Melanges d’Archeologie_, p. 177; for accounts of stamps inscribed with the legend _Diamysus ad Veteres Cicatrices_. [493] _Medicinalium Collectorum_, lib. xiii. p. 499. [494] _Tetrabiblos_, Sermo iii. cap. 37, p. 382. [495] Galen defines Cicatrices and Albugo of the eye as follows:—“_Cicatrix_ appellatur ubi nigro oculi ex alto ulcere membranae crassities supervenit, ut color _albior_ apparet. _Albugo_ nihil a cicatrice differt, nisi quod ex ulcere major cicatrix simul et crassior in iride nascitur.”—Kühn’s Edit. vol. xiii. p. 775. [496] See _Tetrabiblos_, Sermo iii. cap. 40, 37. [497] _Medicæ Artis Principes._ De Collyriis, cap. 72 and 73, p. 665. [498] Dr. Adams’ Translation, vol. i. p. 418. [499] _De Arta Medica_, lib. ii. cap. vi. p. 175. Perhaps the medical idea of staining the cicatrices of the eyes was suggested by the circumstance, that the Romans, like the ancient Egyptians, occasionally had recourse to dyeing or staining their eyebrows in the decorations of the toilet. On the substances (_calliblephara_) used for this purpose, see Pliny, lib. xxiii. cap. 4, and lib. xxxv. cap. 16. Juvenal alludes to the practice in his Second Satire, v. 93:— Ille supercilium madida fuligine tactum Obliqua producit acu, pingitque trementes Attollens oculos. [500] See _Medicæ Artis Principes_. De Medicam. p. 280. [501] In the Minutes of the Society of Antiquaries for 17th November 1757, the word is copied as DELICATA. [502] Thus Nicolaus Myrepsus describes the “Collyrium nominatum _Sol_;” the “Collyrium _Aster_, hoc est stella;” the “Collyrium dictum _Lumen_.” See his _Opus de Compositione Medicamentorum_, sect. xxiv. cap. 2, 22, 3, etc. Trallianus describes the collyrium _Phos_, etc., p. 174. Aetius gives, p. 352, a formula for the collyrium _Uranium_. See also Oribasius, p. 50. Perhaps I ought to have stated earlier, that in quoting the works of Oribasius, Aetius, Myrepsus, Trallianus, Scribonius Largus, and Marcellus, I always refer, except when it is otherwise specified, to the writings of these authors as contained in Stephen’s collated edition of the “_Medicæ Artis Principes post Hippocratem et Galenum_” (Paris, 1567).
