A 1914 lithograph by Lovis Corinth depicting a mentor and student, rendered with the artist's signature expressive, gestural line work.

Warrior's Lesson, or Kriegerlehre, is a lithograph produced by Lovis Corinth in 1914. The work depicts a mature figure positioned behind a younger, smaller individual, who holds a staff or spear. The composition focuses on the physical proximity and the instructional nature of the interaction between the two subjects. Corinth employs a gestural, energetic line quality that is characteristic of his later graphic work, where he moved away from the academic precision of his earlier career toward a more spontaneous, expressive mode of mark-making.

Corinth was a central figure in the transition from late nineteenth-century naturalism to the more subjective approaches of the early twentieth century. His lithographs often demonstrate a raw, immediate quality, capturing the essence of a form through rapid strokes rather than meticulous detail. In this piece, the dark, heavy shadows contrast with the lighter areas of the figures, creating a sense of volume and presence despite the economy of the drawing. The artist's signature is visible at the bottom, alongside the title and date, providing a direct connection to the moment of creation at the onset of the First World War.

The subject matter invites reflection on the transmission of knowledge and the weight of tradition. The older figure appears to guide the younger, their forms merging into a singular, unified silhouette against the plain background. This print demonstrates Corinth's ability to convey psychological tension through posture and gaze. The work remains a clear example of his mastery of the lithographic medium, showing how he used the stone to record his own physical movements and artistic impulses. It is a stark, monochromatic study that relies on the interplay of light and shadow to define the relationship between the two figures.
