2. A physician quoted by Soranus (ap. Gal. De Compos. Medicam. sec. Loc. 1.2, vol. xii. p. 416), Andromachus (ibid. 7.2, vol. xiii. p. 30), and Asclepiades Pharmacion (ap. Gal. De Compos. Medicam. sec. Gen. 3.9, vol. xiii. p. 646), and who lived, therefore, in or before the first century after Christ. He may perhaps be the same person who was called Διορθωτής, Corrector, because, though he was one of the followers of Asclepiades of Bithynia, he ventured to controvert his opinions on some points. (Galen, De Differ. Puls. 4.16, vol. viii. p. 758).

A physician of the same name is mentioned also by Soranus (De Arte Obstetr. p. 184), Plutarch (Sympos. 3.10.2), Alexander Trallianus (1.15, p. 156), Aetius (4.3.13, p. 755), Pliny (Plin. Nat. 19.26.4), and Tertullian (De Anima, 100.15).
