Allatius, Leo

(Leo Allacci in Italian), was born in 1586 of Greek parents in the island of Chio, went to Rome in 1600, and studied at the Greek College in that city. When his course of studies was completed, Bernard Justiniani, bishop of Anglona, selected him for his grand-vicar. In 1621 Pope Gregory XV sent him into Germany to bring to Rome the Palatinate Library of Heidelberg, and Alexander VII made him librarian of the Vatican in 1661. He died Jan. 19, 1669, aged eighty-three, having founded several colleges in his native island. According to Niceron, he was indefatigable in his labors, and possessed a prodigious memory, stored with every kind of knowledge, but he wanted judgment and critical acumen. A list of his writings may be found in Niceron, Memoires, 8, 10. The most important of them are,

1. De Ecclesioe Occident. et Orient. Perpetuad Consensione (Cologne, 1648, 4to): —

2. De utriusque Eccl. etc. in dogmate de Purgatorio Consensione (Rome, 1655, 8vo): —
