"Philology" in the German universities of that age meant Hebrew and Greek. These two languages were generally handled by the same professor, and were taught almost solely to theological students. Wyttenbach's university course at Marburg was troubled about the middle of the time by mental unrest, due to the fascination exercised over him by John Bunyan's Pilgrim's Progress. It was Spangenberg who helped him recover. The principal study of the third year was metaphysics, which took Wyttenbach entirely captive. The fourth and last year was to be devoted to theology and Christian dogma.
