Frans van Ravelingen Latinized Franciscus Raphelengius (February 27, 1539 – July 20, 1597), was a Flemish-born scholar, printer and publisher, working in Antwerp and later in Leiden. During the last decade of his life he was professor of Hebrew at Leiden University. He produced an Arabic-Latin dictionary, of about 550 pages, which was published posthumously in 1613 in Leiden. This was the first publication by printing press of a book-length dictionary for the Arabic language in Latin.
