Abraham, a learned Maronite, associated with Le Jai in the preparation of his Polyglott Bible. He was at first the coadjutor of Gabriel Sionita, a countryman of his, who afterwards quarrelled with him, and brought his case before parliament. In 1636 the congregation de Propaganda Fide associated him with those whom they had employed in making an Arabic translation of the Scriptures; and he removed to Rome for that purpose in 1652. While professor of oriental languages at Rome, he translated into Latin the fifth, sixth, and seventh books of Apollonius's Conics; a task in which he was assisted by John Alphonso Borelli. Ecchellenis died at Rome in 1664.
