Langethal was my teacher for several years. When I knew him he was totally blind, and his eyes, which are said to have flashed so brightly and boldly on the foe in war, and gazed so winningly into the faces of friends in time of peace, had lost their lustre. But his noble features seemed transfigured by the cheerful earnestness which is peculiar to the old man, who, even though only with the eye of the mind, looks back upon a well-spent, worthy life, and who does not fear death, because he knows that God who leads all to the goal allotted by Nature destined him also for no other. His tall figure could vie with Barop's, and his musical voice was unusually deep. It possessed a resistless power when, excited himself, he desired to fill our young souls with his own enthusiasm. The blind old man, who had nothing more to command and direct, moved through our merry, noisy life like a silent admonition to good and noble things. Outside of the lessons he never raised his voice for orders or censure, yet we obediently followed his signs. To be allowed to lead him was an honor and pleasure. He made us acquainted with Homer, and taught us ancient and modern history. To this day I rejoice that not one of us ever thought of using 'pons asinorum,' or copied passage, though he was perfectly sightless, and we were obliged to translate to him and learn by heart whole sections of the Iliad. To have done so would have seemed as shameful as the pillage of an unguarded sanctuary or the abuse of a wounded hero. And he certainly was one! We knew this from his comrades in the war and his stories of 1813, which were at once so vivid and so modest. When he explained Homer or taught ancient history a special fervor animated him; for he was one of the chosen few whose eyes were opened by destiny to the full beauty and sublimity of ancient Greece. I have listened at the university to many a famous interpreter of the Hellenic and Roman poets, and many a great historian, but not one of them ever gave me so distinct an impression of living with the ancients as Heinrich Langethal. There was something akin to them in his pure, lofty soul, ever thirsting for truth and beauty, and, besides, he had graduated from the school of a most renowned teacher. The outward aspect of the tall old man was eminently aristocratic, yet his birthplace was the house of a plain though prosperous mechanic. He was born at Erfurt, in 1792. When very young his father, a man unusually sensible and well-informed for his station in life, entrusted him with the education of a younger brother, the one who, as I have mentioned, afterwards became a professor at Jena, and the boy's progress was so rapid that other parents had requested to have their sons share the hours of instruction.
