Ghevond Alishan largely contributed to Armenian Studies. His researches still remain valuable and continue to amaze scholars by the wide scale of his interests. Being a polyglot he used very diverse and various sources, preferring more study of manuscripts; often his study can gain almost a status of medieval source due to information not found elsewhere. Among other important and manifold material, he touched upon the topic of Armenian monasteries of the Black Mountain, trying to find out their location and giving an important information about them. In this context he dealth with the unique phenomenon of many monasteries at the Black Mountain from 6th to 13th centuries as a centres of teaching and learning and scholarship for different nations. The 11th century was the most flourishing and ‘international’ period for the activities at the Black Mountain’s monasteries; it was sort of international ‘university’ for Greek, Syrian, Latin, Armenian and Georgian monks, ascetics and simply authors, who came in search of a spiritual guide. The monasteries, which belonged to Armenians (at least in the 11th century): Karmir, Shapirin, Areg or Aregni, Vardkan, K’arashit’u, Barsegheanc’, Mashkevor, Paghakdziak, Parlahoy etc. There is information on Armenian personae who came to settle in these monasteries as from Armenian itself (like Georg Megrik, Grigor Lorec’i, Kirakos the Philolog, Mxitar Gosh and many others), as well from Cilician Armenia (Stepanos Manuk, Ignatius Sevlernc’i (of the Black Mountain), Nerses Shnorhali, Grigor the Second, Sargis Shnorhali. Ghevond Alishan gives indispensable testimonies by providing a variety of comprehensive and exhaustive information on the issue under discussion, especially when it concerns relationship of these monasteries with Italy. In this regard, the writing called "Sisuan" is especially important; two chapters of this work are dedicated to the monasteries of the Black Mountain. There he gives the names of the Armenian Catholic monasteries, situated on the Black Mountain; some testimonies concerning these monasteries are taken manuscripts or sources known only to him. Of particular interest are the passages, reporting on the further fate of the monks, who lived there and monasteries, which declined starting from the 13th century, in the result of many invasions and attacks.
