Our analysis reveals that the “Armenian Geography of the VII century” (“Aš­xar­ha­c'oyc'”) was written in the second half of the 610th years and was used as geographical reference by the Armenian delegation, which took part in the fa­mous “Persian Council” in the capital of Sasanian Iran Ktesiphon (615/616 or 617/618 years). Comparison of the texts shows, that the author of this work could have been an Armenian writer of the VI-VII centuries Movsĕs Qerdogh. Three other writings of him has also reached us.
