(Lewis), a very learned Italian, was born at Lucca in Tuscany in 1612. After having finished his juvenile studies, he entered into the congregation of regular clerks of the mother of God, and distinguished himself early by his learning and merit. He taught rhetoric seven years, and passed through several offices of his order. He applied himself principally to the study of languages, and attained of himself the knowledge of the Greek, the Hebrew, the Syriac, the Chaldee, the Arabic; which last he taught some time at Rome, by the order of pope Alexander VII. Pope Innocent XI. chose him for his confessor, and placed great confidence in him. He would have advanced him to ecclesiastical dignities, if Marracci had not opposed him.—Marracci died at Rome in 1700, aged 87.—He was the author of several pieces in Italian; but the grand work, which has made him deservedly famous all over Europe, is his edition of the Alcoran, in the original Arabic, with a Latin version, notes, and confutation of his own. It was beautifully printed in 2 vols folio at Padua in 1698. The Latin version of the Alcoran, by Marracci, with notes and observations from him and others, and a synopsis of the Mahometan religion, by way of introduction, was published by Heiniccius at Leipzig, 1724, in 8vo. Marracci had also a hand in the "Biblia sacra Arabica, sacra congregationis de propaganda fide jussu edita, ad usum ecclesiarum orientalium," Rome 1671, in 3 vols folio.
