At Bonn Nietzsche became a student of Ritschl, the famous philologist,[1] and when Ritschl left Bonn for Leipsic, Nietzsche followed him. All traces of the good fellow had disappeared and the student that remained was not unlike those sophomores of medieval Toulouse who "rose from bed at 4 o'clock, and having prayed to God, went at 5 o'clock to their studies, their big books under their arms, their inkhorns and candles in their hands." Between teacher and pupil there grew up a bond of strong friendship. Nietzsche was taken, too, under the wing of motherly old Frau Ritschl, who invited him to her afternoons of coffee and cinnamon cake and to her evening soirées, where he met the great men of the university world and the eminent strangers who came and went. To Ritschl the future philosopher owed many things, indeed, including his sound knowledge of the ancients, his first (and last) university appointment and his meeting with Richard Wagner. Nietzsche always looked back upon these days with pleasure and there was ever a warm spot in his heart for the kindly old professor who led him up to grace. Two years or more were thus spent, and then, in the latter part of 1867, Nietzsche began his term of compulsory military service in the fourth regiment of Prussian field artillery. He had hoped to escape because he was near-sighted and the only son of a widow, but a watchful _oberst-lieutenant_ found loopholes in the law and so ensnared him. He seems to have been some sort of officer, for a photograph of the period shows him with epaulets and a sword. But lieutenant or sergeant, soldiering was scarcely his forte, and he cut a sorry figure on a horse. After a few months of unwilling service, in fact, he had a riding accident and came near dying as his father had died before him. As it was he wrenched his breast muscles so badly that he was condemned by a medical survey and discharged from the army. During his long convalescence he busied himself with philological studies and began his first serious professional work--essays on the Theogony of Hesiod, the sources of Diogenes Laërtius and the eternal strife between Hesiod and Homer. He also made an index to an elaborate collection of German historical fragments and performed odd tasks of like sort for various professors. In October, 1868, he returned to Leipsic--not as an undergraduate, but as a special student. This change was advantageous, for it gave him greater freedom of action and protected him from that student _bonhomie_ he had learned to despise. Again old Ritschl was his teacher and friend and again Frau Ritschl welcomed him to her _salon_ and gave him of her good counsel and her excellent coffee.
