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.
Trosius Aper Trosius Aper was a grammarian of ancient Rome who served as one of two Latin tutors for the Roman emperor Marcus Aurelius, along with Tuticius Proculus. He was from Pola (modern Pula) in Istria, and was assigned to Aurelius as a tutor around 132 or 133. As a tutor, Aper would have Aurelius read classical works out loud, and memorize them, later commenting on stylistic matters, and drawing philosophical lessons from the text for his pupil.
