Ambrose

, a monk, and general of the monks of Camalduli, was born in 1373, at Portico in the Romagna. | Eugene IV. sent him to the council of Basil, where he much distinguished himself, as well as at those of Ferrara and Florence. He acquired a high degree of reputation by his profound knowledge of the Greek language, by his uncommon acquaintance with Grecian literature, by the zeal and industry he discovered in the attempts he made to effectuate a reconciliation between the Greek and Latin churches. He was no less admired for his candid and liberal spirit, and placid and serene temper. Having failed in an attempt to reconcile those literary rivals Poggius and Valla, he told them that men who made use of abusive language could not be supposed to possess either the charity of Christians, nor the politeness of men of letters. His talents would have recommended him to the purple, which the pope intended, but this was prevented by his death, Oct. 23, 1439. He was employed, J>y order of pope Eugenius IV. to reform several convents of both sexes, which had become irregular; and he has described the result of his labours in this difficult work in his “Hodseporicon,” which contains particulars of the behaviour of the inhabitants of those convents, which he found it necessary to express in Greek. This was printed at Florence, 1431 and 1432, 4to, both scarce editions, and 1678, 8vo. The other works of this learned monk were Latin translations from the fathers. Martenne, in his “Collectio amplissima,” has published twenty books of his letters, which contain many curious particulars of the history of his time. He also translated Diogenes Laertiusinto Latin, which was printed at Venice, 1475, and is a book of great price, as being prior in date by nearly sixty years to any edition of that author. 1
