Oribasius
ancient Greek physician

Oribasius or Oreibasius (Greek: Ὀρειβάσιος or Ὀριβάσιος; c. 320 – 403) was a Greek medical writer and the personal physician of the Roman emperor Julian. He studied at Alexandria under physician Zeno of Cyprus before joining Julian's retinue. He was involved in Julian's coronation in 361, and remained with the emperor until Julian's death in 363. In the wake of this event, Oribasius was banished to foreign courts for a time, but was later recalled by the emperor Valens.
Works
Oribasius's major works, written at the behest of Julian, are two collections of excerpts from the writings of earlier medical scholars, a collection of excerpts from Galen and the Medical Collections (Ἰατρικαὶ Συναγωγαί, Iatrikai Synagogai; Latin: Collectiones medicae), a massive compilation of excerpts from other medical writers of the ancient world. The first of these works is entirely lost, and only 25 of the 70 (or 72) books of the Collectiones survive. This work preserves a number of excerpts from older writers whose writings have otherwise been lost, and has thus been valuable to modern scholars. The earliest known description of a string figure, presented as the surgical sling Plinthios Brokhos by Greek physician Heraklas, is among the preserved material.
Hagiography has it that in 362, on behalf of his emperor Julian, Oribasius visited the Delphic oracle, now in a rather desolate state, offering his emperor's services to the temple and, in return, receiving one of the last prophecies by the Delphic Pythia:
Εἴπατε τῷ βασιλεῖ, χαμαὶ πέσε δαίδαλος αὐλά,
οὐκέτι Φοῖβος ἔχει καλύβην, οὐ μάντιδα δάφνην,
οὐ παγὰν λαλέουσαν, ἀπέσβετο καὶ λάλον ὕδωρ.
This brief starts where responsible research should: with the source description of “Oribasius” as ancient Greek physician. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as ancient Greek physician. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jun 20, 2026. The linked authority identifier is Q953784. VIAF identifies the subject as 7440344. The Library of Congress control number is n86816961. 3 of 5 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
