ALLACCI, LEONE (LEO ALLATIUS) 0586-1669), Greek scholar and theologian, and a voluminous writer, was born in the island of Chios. His early years were passed in Calabria and at Rome, where he finally settled as teacher of Greek at the Greek college, at the same time devoting himself to the study of classics and theology. Allacci was sent to superintend the removal to Rome of the 196 cases of mss. from Heidelberg presented by the elector Maximilian of Bavaria to Pope Gregory XV. This collec tion (bibliotheca Palatina) was incorporated with the Vatican library. On the death of Gregory, Allacci became librarian to Cardinal Berberini, and subsequently 0660 librarian of the Vatican, which post he held till his death.
