I. Franciscus Junius (Francois du Jon), a Protestant theologian, born in Bourges, France, in 1545, died in Leyden in 1602. He was designed for the law, but having embraced the doctrines of the reformation, he went in 1562 to Geneva, where he studied theology. He became minister of a Walloon congregation in Antwerp in 1565, and took a prominent part in the early history of the reformation in the Netherlands, but was obliged to seek refuge in Germany. In 1573 he was invited by the elector palatine to Heidelberg, where, in conjunction with Tremellius, he made a Latin translation of the Old Testament, which is highly esteemed by critics (5 parts, Frankfort, 1575-9 ; many times reprinted, last in Zurich, 1764). Subsequently he became professor at Leyden. He wrote many theological books, and an autobiography (1595). His Opera The-ologica were published in 2 vols. fol. (Geneva, 1607). II Franeiscus, a philologist, son of the preceding, born in Heidelberg in 1589, died in Windsor, England, Nov. 19, 1677. He studied at Heidelberg and Leyden with a view to the profession of a military engineer, and in 1603, after the death of his father, joined the army; but leaving it on the truce of 1609, he devoted himself to study and literature.

In 1620 he went to England, and for 30 years filled the office of librarian to the earl of Arundel. During this period he studied the Teutonic languages, and came to the conclusion that the Gothic was the parent of them all. He published an edition of the Gothic Gospels of Ul-filas, with a commentary: but his greatest work was his Glossarium Gothicum, in five languages', the Saxon department of which has since been issued separately under the title of Etymologicum Anglicanum. He also wrote a treatise De Pictura Veterum, which he translated into English himself. In 1650 he visited Germany, and remained there for some years. He died while residing in the house of his nephew, Isaac Vossius. He bequeathed all his MSS. to the Bodleian library at Oxford.
