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.
Al-Tirmidhi Abū ‘Īsá Muḥammad ibn ‛Īsá as-Sulamī aḍ-Ḍarīr al-Būghī at-Tirmidhī (Arabic: أبو عيسى محمد بن عيسى السلمي الضرير البوغي الترمذي‎ ‎ ; Persian: ‎ ‎ , "Termezī"; 824 – 9 October 892), often referred to as Imām at-Termezī/Tirmidhī, was a Persian Islamic scholar and collector of hadith who wrote "al-Jami` as-Sahih" (known as "Jami` at-Tirmidhi"), one of the six canonical hadith compilations in Sunni Islam. He also wrote "Shama'il Muhammadiyah" (popularly known as "Shama'il at-Tirmidhi"), a compilation of hadiths concerning the person and character of the Islamic prophet, Muhammad. At-Tirmidhi was also well versed in Arabic grammar, favoring the school of Kufa over Basra due to the former's preservation of Arabic poetry as a primary source.
