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.
Pinakes The Pinakes (Ancient Greek: Πίνακες "tables", plural of πίναξ ) is a lost bibliographic work composed by Callimachus (310/305–240 BCE) that is popularly considered to be the first library catalog; its contents were based upon the holdings of the Library of Alexandria during Callimachus' tenure there during the third century BCE.
