The Oise near Pontoise in Grey Weather

The Oise near Pontoise in Grey Weather at Museum Boijmans Van Beuningen, painted in 1876, shows Pissarro's most characteristic meteorological condition: the overcast, grey-sky weather of the Île-de-France that prevailed for much of the year and that demanded a very different chromatic approach from the sunlit brilliance more typically associated with Impressionism. Where Monet's reputation was built partly on his ability to render the effects of intense sunlight — the glittering water of Argenteuil, the dissolving facades of Rouen Cathedral in bright noon — Pissarro's approach embraced the grey, diffuse light of overcast days with equal commitment. The tonally restricted palette this required — subtle distinctions between cool grey water, pale grey sky, and the muted greens of willow-lined banks — demanded great precision of chromatic observation without the easier pleasures of saturated colour. Boijmans Van Beuningen's holding of this grey-weather Pissarro allows comparison with the sunlit Pontoise canvases that have dominated his public image, revealing the full range of his meteorological investigation.

The palette is restricted to cool greys, pale blues, and muted greens appropriate to the overcast day. Pissarro builds the river's surface with horizontal strokes of subtly varied tones. The poplar trees on the banks are indicated with vertical, upward marks. The composition is horizontal and meditative, avoiding strong focal points.
