3. A pupil of Erasistratus in the third century B. C., who appears to have lived on very intimate terms with his tutor. (D. L. 5.3.61 ; Galen. De Ven. Sect. adv. Erasistr. Rom. Deg. 100.2, vol. xi. p. 197; Oribas. Coll. Medic. 45.23, p. 60, ed. Mai.) He wrote a work to explain the difficult words found in the writings of Hippocrates, which is mentioned by Erotianus (Gloss. Hippocr. s. v. ἄμβην). Like the rest of the followers of Erasistratus, he was averse to blood-letting (Galen. De Ven. Sect. adv. Erasistr. 100.2, vol. xi. p. 151), but could not give any very good reasons for his opinion. He is probably the physician quoted by Alexander Trallianus (1.15, pp. 156, 157), and Aetius (1.2, 3, 4.1, 7, 46, pp. 64, 616, 628). He was tutor to Apollonius of Memphis (Galen. De Diff. Puls. 4.17, vol. viii. p. 759), and not his father, as some have supposed. [APOLLONIUS * Straton is here too positively said to have been the native of Berytus; he ought to have been called the follower of Erasistratus, who may possibly have been " the native of Berytus," but cannot be proved to have been so., p. 246.] See Sprengel's Gesch. der Arzneik. vol. i. pp. 559, 561, ed. 1846.
