a Greek scholar, theologian, and keeper of the Vatican library. In 1622, after the capture of Heidelberg by Tilly, when the Protestant Elector of Bavaria Frederick V was supplanted by a Catholic one, the victorious elector Maximilian of Bavaria presented the Palatinate library composed of 196 cases containing about 3500 manuscripts to Pope Gregory. Allatius supervised its transport by a caravan of 200 mules across the Alps to Rome, where it was incorporated in the Vatican library. All but 39 of the Heidelberg manuscripts, which had been sent to Paris in 1797 and were returned to Heidelberg at the Peace of Paris in 1815, and a gift from Pope Pius VII of 852 others in 1816, remain in the Vatican Library to this day.
