Orbelian is known to have completed three works during his lifetime: the
History of the Province of Syunik (
Patmutʻiwn Nahangin Sisakan) in 1297; the
Lament on Behalf of the Cathedral (
Voghb i dimatsʻ surb Katʻoghikēin), where he calls on the Armenians to repopulate
historic Armenia, which was under Mongol rule at the time, in 1300; and the
Argument Against Dyophysitism (''Hakacharut'iun unndem yerkabnakats'''), in 1302, a work criticizing the pro-Byzantine and Westernizing tendencies of
Grigor VII Anavarzetsi of Cilicia. Of the three, the most prominent is that on the history of Syunik and the Orbelian family. Before he began writing it, he conducted an extensive amount of research, utilizing a wide variety of sources derived from speeches, letters,
colophons, previous histories and chronicles by Armenian historians, as well as works by
Georgian authors. Like other Armenian historians and chroniclers, Orbelian's work briefly narrates the beginning of the world starting with
Adam and Eve, but then moves on to tell Syunik's and Armenia's history, spanning from the time of king
Tiridates I to the end of the thirteenth century. Orbelian's work is especially valuable as it contains many previously unknown details about the province and Armenian history. In 1864 and 1866, Orbelian's
History of the Province of Syunik was translated into
French (with excerpts translated into
Georgian and
Russian) by
orientalist Marie-Félicité Brosset. A translation into modern Armenian was published by linguist Ashot Abrahamyan in 1986. Robert Bedrosian published an English translation of Orbelian's history in 2012. A Russian translation of the history by
Margarita Darbinyan was published in 2020. ==References==
