The Narratio de rebus Armeniae is a history of relations between the Armenian and Greek churches written around AD 700. It is not exclusively focused on ecclesiastical affairs and also touches on Armenian relations with the Roman Empire. It was originally written in Armenian, but the complete text is known only from a Greek translation, entitled Diegesis, made before the eleventh century, possibly as early as the eighth. Although there are later Armenian writers who cite the Armenian version, it is now lost.
