Matenadaran
The Matenadaran, officially the Mesrop Mashtots Institute of Ancient Manuscripts, is a museum, repository of manuscripts, and a research institute in Yerevan, Armenia. Currently, the Matenadaran contains a total of some 23,000 manuscripts and scrolls —including fragments. The manuscripts cover a wide array of subjects: religious and theological works, texts on history, mathematics, geography, astronomy, cosmology, philosophy, jurisprudence, medicine, alchemy, astrology, music, grammar, rhetoric, philology, pedagogy, collections of poetry, literary texts, and translations from Greek and Syriac. The writings of classical and medieval historians Movses Khorenatsi, Yeghishe and Koryun are preserved here, as are the legal, philosophical and theological writings of other notable Armenian figures. The preserved writings of Grigor Narekatsi and Nerses Shorhali at the Matenadaran form the cornerstone of medieval Armenian literature.
