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.
Scholarch A scholarch (Ancient Greek: σχολάρχης , "scholarchēs") was the head of a school in ancient Greece. The term is especially remembered for its use to mean the heads of schools of philosophy, such as the Platonic Academy in ancient Athens. Its first scholarch was Plato himself, the founder and proprietor. He held the position for forty years, appointing his nephew Speussipus as his successor; later scholarchs were elected by members of the Academy.
