Mnaseas is reckoned to have been a pupil of a scholar who was chief librarian at what library?
Mnaseas Mnaseas of Patrae (Ancient Greek: Μνασέας ὁ Πατρεύς ) or of Patara, whether that in Lycia or perhaps the Patara in Cappadocia was a Greek historian of the late 3rd century BCE, who is reckoned to have been a pupil in Alexandria of Eratosthenes. His "Periegesis" or "Periplus" described Europe, Western Asia and North Africa, but whether in six or eight books cannot now be determined. His "On Oracles" appears to have consisted of a catalogue of oracular responses with commentary. Only fragments of his work survive, some found in fragmentary papyri at Oxyrhynchus, others embedded as scholia or as quotations in other works, often selected, apparently, because of the unusual interpretations they offer.
Hegias Hegias (Greek: Ἡγίας ) was a Neoplatonist philosopher who lived in the 5th and 6th centuries. He may have been the great-grandson or great-great-grandson of Plutarch of Athens, the founder of the Neoplatonist Academy in Athens. Hegias studied under Proclus at the school in Athens, when Proclus was an old man c. 480. Proclus showed him great favour, and considered him worthy of hearing his lectures on the Chaldean Oracles.
