Clieon

(Κλέων), an oculist who must have lived some time before the beginning of the Christian era, as he is mentioned by Celsus. (De Medic. 6.6. §§ 5, 8, 11, pp. 119-121.) Some of his prescriptions are also quoted by Galen (De Compos. Medicam. sec. Locos, 3.1, vol. xii. p. 636), Aetius (Lib. Medic. 2.2. 93, 2.3. 15, 18, 27, 107, pp. 294, 306, 309, 353), and Paulus Aegineta. (De Re Med. 7.16, p. 672.) [W.A.G]
