Alberti, Johann, a German lawyer and scholar of the 16th century, was born at Widmanstadt, and became deeply versed in the Oriental languages. He died in 1559. He published an abridgment of the Koran, with critical notes (1543, 4to), which procured him the title of chancellor of Austria and chevalier of St. James; and a New Testament in Syriac, from a manuscript used by the Jacobites, at the expense of Ferdinand I (1556, 4to). It contains neither the second epistle of Peter, nor the second and third of John, nor Jude, nor the Apocalypse. Only one thousand copies were printed. He also composed a Syriac grammar.
