Influenced partly by the fact that Gregory was the son of his father's enemy, he ordered Gregory imprisoned for twelve (some sources indicate fourteen) years in a pit on the Ararat Plain under the present day church of Khor Virap located near the historical city Artashat in Armenia. Gregory was eventually called forth from his pit in c. 297 to restore to sanity Tiridates III, who had lost all reason after he was betrayed by Roman emperor Diocletian.
