Theological Institute of Connecticut blind-stamps to first and last few pages. Very rare. Very good. FIRST EDITION of Morcelli’s presentation of Leontios’ life of St. Gregory of Agrigento. Besides a collection of letters surviving the Roman patrimony in Sicily, "only one other contemporary source about seventh-century Sicily and Rome survives:. . . (An account of the life of Saint Gregory, bishop of the church of Agrigento), written in about 640 by a Greek monk, Leontios, abbot of the monastery of Saint Sabas near the gate to Ostia in Roma" (Martyn, p. 26). "The standard Greek text has a parallel Latin version by Stephano Antonio Morcelli. . .. This is preceded by an investigatio by Morcelli of the monk Leontios. . .and followed by an account of the Sicilian saint’s life, heavenly honors, and writings. . ., as well as Gregory’s Explanatio super Excclesiasten libri I-X. . ., also in Greek with Morcelli’s Latin version alongside. "This biography is useful in showing how the pope selected bishops. Born in 559, this Gregory was consecrated (when he was a little over 30 years old) in place of one of two eminent clerics sent over with their supporters from Agrigento, for the pope to decide. It shows how a ‘framed’ bishop was imprisoned and tried, how well trained he was in the Classics, rhetoric, and theology, and how he was miraculously able to fast continually and cure illnesses. This Greek biography is an important, contemporary document on the cities, clergy and people of Agrigento, Jerusalem, Antioch, Constantinople and Rome during Gregory’s papacy" (Martyn, p. 26). Unofficial ecclesiastical sources identify St. Gregory of Agrigento as a 6th-century Italian bishop, not to be confused with his contemporary, Pope St. Gregory the Great. "Gregory was born in the sixth century AD near the town of Agrigentum, in Sicily. He was ordained a deacon while on Pilgrimage to the Holy Land and was later consecrated bishop of Agrigentum in Rome, serving during the time of Pope St. Gregory the Great, who addressed several letters to him. He died around 594, and is regarded as one of the Early Church Fathers (D’Ambrosio).
