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.
Orion of Thebes Orion of Thebes (died c. 460s) was a 5th-century grammarian of Thebes (Egypt), the teacher of Proclus the neo-Platonist, and of Eudocia, the wife of Emperor Theodosius II. He taught at Alexandria, Caesarea in Cappadocia and Constantinople. He was the author of a partly extant etymological Lexicon (ed. F. W. Sturz, 1820), largely used by the compilers of the "Etymologicum Magnum", the "Etymologicum Gudianum" and other similar works; a collection of maxims in three books, addressed to Eudocia, also ascribed to him by Suidas, still exists in a Warsaw manuscript.
