Encyclopedia
Anania Shirakatsi ( also known as Ananias of Shirak; 610 – 685) was an Armenian mathematician, astronomer and geographer. His most famous works are Geography ("Ashkharatsuyts" in Armenian), and Cosmography (Tiezeragitutiun).
Life
Scholars are split on where exactly Anania was born. According to some historians, he was born in Shirakavan, whereas others maintain that the village of Anania in Shirak or the city of Ani were his birthplaces. Unlike many other notable figures, Anania did leave behind an autobiography. He was the son of John (Hovhannes) of Shirak and possibly a member of the noble Kamsarakan or Arsharuni princes of the region. It is believed that he received his primary education at a school named Dprevank and from a very early age, he found himself attracted to mathematics. He left Armenia and traveled abroad for eleven years in the hopes of getting a better education.
Upon the recommendation of several of his friends who were returning from Constantinople, he decided to find a suitable teacher in Trebizond in the Byzantine Empire. There he met and fell under the tutelage of a renowned Greek scholar who spoke Armenian, Tychikos, and spent eight years learning mathematics there. Anania profited greatly from his mentor's teachings, as evidenced from the writings in his autobiography, "[I] acquired a perfect knowledge of mathematics. In addition, I also learned a few elements of other sciences." He left Byzantium and returned to his homeland in 651, determined to spread his knowledge among his fellow Armenians, opening a school that taught the quadrivium and authoring textbooks to educate his students.
Works
Armenian calendar
The education center Anania established could not have come at a better time and was a welcoming sight during an era when the study of mathematics was waning. After teaching for only several years, he had gained a famous reputation all throughout Armenia and abroad. The beginning of one of his most significant accomplishments came in 667 when the Armenian Apostolic Church invited him to Dvin and asked him to modify the Armenian calendar from a movable to fixed system.
Taking into account the incompatibilities of the seven day week, the lunar month, and the solar year, he worked for two years and devised a system that was based on cycle of 532 years. Anania's solution, though, was never put into effect.
Geography
Among all his works, Anania is best known for writing the Ashkharatsuyts (Geography), a historical atlas that gives detailed information on the 15 provinces of Armenia. Anania gives general information on the "the earth, its surface, climatic belts, seas" and also includes information on Armenia's neighbors. Up until recently attributed to Armenian historian Movses Khorenatsi but is now widely believed by experts such as Robert Hewsen and Suren T. Yeremyan to have been authored by Anania himself. Babken Harutyunyan, head of Chair of the History of Armenia at Yerevan State University, however disputes this and maintains that Movses Khorenatsi was the true author on the basis "that all the manuscripts of the 'Ashxarhatsoyts' preserving the author's name, without exception, point at the Patmahayr [father of history] Movses Xorenatsi as an author of the work."
The Ashkharatsuyts reports details and mapping of the ancient homeland of Bulgars in the Mount Imeon area of Central Asia. The oldest manuscript in the field of Armenian geography preserved at the Matenadaran in Yerevan is Anania's Ashkharatsuyts.
Astronomy
Anania also authored Cosmography and the Calendar, a 48 chapter work that discusses astronomy, meteorology, and physical geography. He described the world as "being like an egg with a spherical yolk (the globe) surrounded by a layer of white (the atmosphere) and covered with a hard shell (the sky)."
Legacy
Anania is considered the founder of the study of the natural sciences in Armenia. For centuries, his works were used at schools in Armenia as textbooks. The Anania Shirakatsi Medal is an Armenian State Award for scientists in the economics and natural sciences, engineers and inventors. In 2005, the Central Bank of the Republic of Armenia issued an Anania Shirakatsi commemorative coin.
