Glaucias (Greek: Γλαυκίας; c. 3rd century BC) was a Greek physician of the Empiric school who wrote commentaries on the works of Hippocrates.
He belonged to the Empiric school,[1] and lived after Serapion of Alexandria, and before Heraclides of Tarentum, and therefore probably in the 3rd or 2nd century BC.
[2] Galen mentions him as one of the earliest commentators on the whole of the Hippocratic Corpus,[3] and he also wrote an alphabetical glossary on the difficult words occurring in the Hippocratic collection.
[4] His commentaries on Hippocrates are several times quoted and referred to by Galen.
[5] It is uncertain whether he is the person quoted by Pliny.
