Harpocras

(Ἁρπόκρας), an iatralipta, who attended the younger Pliny, with great care and assiduity, about the beginning of the second century after Christ. He was originally a slave, was afterwards manumitted, and lastly, at the especial request of Pliny, presented by the emperor Trajan with the freedom of the cities of Rome and Alexandria. (Plin. Ep. 10.5, 6.) He is not the same person whose prescriptions are several times quoted by Androachus (ap. Galen. De Compos. Medicam. sec. Gen. vol. xiii. pp. 729, 838, 841, 978), and who must have lived about a hundred years earlier. [W.A.G]
