(Ἥρας), a physician of Cappadocia, who lived after Heracleides of Tarentum (Galen, De Compos. Medicam. sec. Gen. 5.6, vol. xiii. p. 812), and before Andromachus (Galen, De Compos. Medicam. sec. Loc. 6.9, vol. xii. p. 989), and therefore probably in the first century B. C. He wrote some works on pharmacy, which are very frequently quoted by Galen, but of which nothing but a few fragments remain. His prescriptions are quoted also by other ancient medical writers, and he may perhaps be the physician mentioned by Martial (Epigr. 6.78. 3). See C. G. Kühn, Additam. ad Elench. Medic. Vet. a J. A. Fabric. in "Bibl. Graeca " exhibitum.
