Foremost among his writings are the "Letters," which are 80 in number, and which shed light upon the political and religious problems of the time. His poetry bears the impress of both Homeric Greek and the Arabic of his own century. His chief poetical work is a long metrical narrative of the principal events recorded in the Bible. This work was purportedly written in three days in 1045 at the request of a Muslim scholar, who, after reading it, converted to Christianity. Grigor was almost the first poet to adopt the use of rhyme introduced to Armenia by the Arabs.
