The following are the most valuable of their contributions to the common cause of learning. Firstly the recovery, in ancient Armenian translations, of some lost works of the Fathers of the Church. Among them may be noted "Letters (thirteen) of St. Ignatius of Antioch" and a fuller and more authentic "History of the Martyrdom of St. Ignatius"; some works of St. Ephrem the Syrian, notably a sort of "Harmony of the Gospels" and a "Commentary on the Epistles of St. Paul"; an edition of Eusebius's "Ecclesiastical History". The publication of these works is due to the famous Mekhitarists Dom Pascal Aucher, who was assisted in the last of them by Cardinal Mai. Pascal Aucher (Harut'iwn Awgerian: 1774–1855) also became Lord Byron’s tutor in Armenian, and his "spiritual pastor and master". He translated Paradise Lost into Armenian (1824). To Aucher also we are indebted for a German translation of the "Armenian Missal" (Tübingen, 1845) and "Dom Johannis philosophi Ozniensis Armeniorum Catholici (AD 718) Opera" (Venice, 1534).
