Oribasius

Oribasius (c. 320-400/403 CE) was the physician and political advisor of the Roman emperor Julian the Apostate (r. 361-363 CE). A native of Pergamon, a rich and powerful Greek city in Mysia, he studied medicine and oratory and belonged to the high intellectual circle of Pergamon. Oribasius was an iatrosophist, which refers to a physician of a special rhetorical and philosophical knowledge, and a great admirer of Galen's medical knowledge and polymathy. His most famous work is Iatrikai synagogai or Collectiones medicae, a medical treatise of great significance.
