Aristakes Lastiverts'i was an eleventh century Armenian cleric and historian.
His History was written between 1072 and 1079, and describes the events of 1000-1071, including information about Byzantine-Armenian relations, the Seljuk invasions, and the Tondrakian movement in the Armenian Church.
The work opens with a poetic summary of the disasters befalling the Armenian people in the eleventh century.
Subsequent chapters describe Byzantine attempts to subjugate the Armeno-Georgian di.
