HAGEN, MARTIN. - Jesuit, exegete, brother of the astronomer Johannes Georg, born at Bregenz (Austria) on 23 May 1855, died at Valkenburg (Holland) on 12 July 1923. Professor of Hebrew and Sacred Scripture, first at Ditton Hall (1891–95), then at Valkenburg (1895–1907), and later writer and collaborator of the *Cursus Scripturae Sacrae*, founded and directed by Fr R. Cornely.
To the *Cursus* indeed belong his principal works: *Lexicon biblicum* (3 vols., Paris 1905–11); *Atlas biblicus* (ibid. 1907); the 6th, 7th, and 8th updated and complete editions of the *Compendium introductionis historicae et criticae in utriusque Testamenti sacros libros* by Fr R. Cornely (ibid. 1909, 1911, 1914) and the complementary volume: *Realia biblica geographica, naturalia, archaeologica* (ibid. 1914); the 2nd updated and complete edition of the *Commentarius in Prophetas minores* by Fr J. Knabenbauer (2 vols., ibid. 1924). To these scholarly labours H. also wished to add several ascetical works, the fruit of his spiritual ministry: *Das Herz Jesu, die Gnadenstunde an der Wende des Jahrhunderts* (Kevelaer 1899; Italian ed. Vicenza 1901); *Die göttlichen Tugenden* (ibid. 1909); *Die sittlichen Tugenden* (ibid. 1910).
