Two trees silhouetted behind a water course

Two trees silhouetted behind a water course of 1901 is a composition of remarkable simplicity and proto-modernist directness — two tree forms, dark against the sky, reflected in water below. The trees are stripped of identifying botanical character by the silhouette treatment, becoming pure form rather than species. This formal reduction anticipates the tree studies of 1908–1912 in which Mondrian progressively abstracted tree forms into rhythmic networks of lines. At this earlier moment, the silhouette approach is still naturalistic in intention but formally already pushing toward abstraction.

The silhouetted trees are rendered in dark tones against a lighter sky, their forms reduced to outline and mass. The water course below provides the reflection — soft, dark forms inverted and slightly blurred. The composition is almost entirely tonal: dark forms against pale ground. The simplicity of this tonal strategy is its strength and its forward-looking quality.
