In January 1778 the poet J.M.R. Lenz walked over the Vosges mountains to the parsonage of Pastor Johann Friedrich Oberlin at Waldersbach. There his calm alternated with terror: he threw himself into a fountain at night, tried to raise a dead child in the village of Fouday, and made repeated suicide attempts. Oberlin finally had him taken under guard to Strasbourg, and the text ends with Lenz living on in blank, empty indifference ('So lebte er hin').
The third-person narrator slides into Lenz's perceptions without marking the shift, so the reader takes in his distortions as plain description of the world. The famous opening, 'only it sometimes annoyed him that he could not walk on his head', states an impossible wish in the same flat tone as the mountain scenery. This removes the clinical distance a case report keeps and makes the reader share the disorder instead of diagnosing it.
In the 'Kunstgespräch' (art conversation), Lenz argues that the only test of art is whether it has life, not whether it is beautiful. The artist should love the humblest, ugliest person enough to enter into their particular way of being, rather than painting idealized figures. Idealism, in his words, is the most shameful contempt for human nature.
Landscape in the text is not a setting but a measure of Lenz's inner state: at first he feels he could pull the universe into himself, and later the world goes empty, cold, and 'hollow'. Watching how a mind relates to its surroundings, whether through fusion, terror, or deadened indifference, shows psychological collapse more exactly than any account of its causes. The endpoint of the collapse is not frenzy but a total loss of feeling.
