[4] According to Merx (op. cit. p. 43) this may be the celebrated convent of Eusebius near Apamea.
[5] Assemani tried hard to prove him orthodox (B.O. i. 470 sqq.) but changed his opinion on reading his biography by Barhebraeus (ib. ii. 337). See especially Lamy, Dissert. de Syrorum fide, pp. 206 sqq.
[6] Text at Leipzig 1889 (Das Buch der Erkenntniss der Wahrheit oder der Ursache aller Ursachen): translation (posthumously) at Strassburg 1893.
[7] The surviving fragments were published by Wright (London, 1871) and by Merx, op. cit. p. 73 sqq. of Syriac text.
[8] An affirmative answer is given by Wiseman (Horae syr. pp. 181-8) and Wright (Catalogue 1168; Fragm. of the Syriac Grammar of Jacob of Edessa, preface; Short Hist. p. 151 seq.). But Martin (in Jour. As. May-June 1869, pp. 456 sqq.), Duval (Grammaire syriaque, p. 71) and Merx (op. cit. p. 50) are of the opposite opinion. The date of the introduction of the seven Nestorian vowel-signs is also uncertain.
JACOB OF JÜTERBOGK (c. 1381-1465), monk and theologian. Benedict Stolzenhagen, known in religion as Jacob, was born at Jüterbogk in Brandenburg of poor peasant stock. He became a Cistercian at the monastery of Paradiz in Poland, and was sent by the abbot to the university of Cracow, where he became master in philosophy and doctor of theology. He returned to his monastery, of which he became abbot. In 1441, however, discontented with the absence of strict discipline in his community, he obtained the leave of the papal legate at the council of Basel to transfer himself to the Carthusians, entering the monastery of Salvatorberg near Erfurt, of which he became prior. He lectured on theology at the university of Erfurt, of which he was rector in 1455. He died on the 30th of April 1465.
Jacob’s main preoccupation was the reform of monastic life, the grave disorders of which he deplored, and to this end he wrote his Petitiones religiosorum pro reformatione sui status. Another work, De negligentia praelatorum, was directed against the neglect of their duties by the higher clergy, and he addressed a petition for the reform of the church (Advisamentum pro reformatione ecclesiae) to Pope Nicholas V. This having no effect, he issued the most outspoken of his works, De Septem ecclesiae statibus, in which he reviewed the work of the reforming councils of his time, and, without touching the question of doctrine, championed a drastic reform of life and practice of the church on the lines laid down at Constance and Basel.
His principal works are collected in Walch, Monimenta med. aev. i. and ii. (1757, 1771), and Engelbert Klüpfel, Vetus bibliotheca eccles. (Freiburg-im-Breisgau, 1780).
