GOLIUS or GOHL, JACOBUS (1596-1667), Dutch orien talist, born at The Hague, studied at the University of Leyden, where in Arabic and other Eastern languages he was a pupil of Erpenius. In 1622 he accompanied the Dutch embassy to Mo rocco, and on his return he was chosen to succeed Erpenius (1624). He then spent five years travelling in Syria and Arabia. The remainder of his life was spent at Leyden where he held the chair of mathematics as well as that of Arabic. He died on Sept. 28, 1667. His most important work is the Lexicon Arabico-Lati num (Leyden, 1653), which, based on the Sihah of Al-Jauhari, was only superseded by the corresponding work of Freytag. In 1656 he published a new edition, with considerable additions, of the Gru.mmatica Arabica of Erpenius. After his death, there was found among his papers a Dictionarium Persico-Latinum which was published, with additions, by Edmund Castell in his Lexicon heptaglotton (1669).
