Frost

Frost from 1880 at the Musée d'Orsay was painted during or just after the catastrophic winter of 1879–80, the coldest in France for nearly a century. The Seine had frozen completely in late December 1879 and stayed frozen through January 1880, when the dramatic thaw produced the ice-floe débâcle that Monet painted with extraordinary intensity. Frost subjects — the landscape coated in the delicate grey-white of heavy rime — interested him as a variant on snow, one that preserved the landscape's forms more than deep snow while transforming every surface with its crystal deposit. Where snow eliminated details and simplified masses, frost revealed them with a strange crystalline clarity. Monet had been exploring winter atmospheric effects since his Norman snow paintings of the late 1860s, and the Vétheuil winter campaigns represent the full maturation of that interest. Sisley, who was making his finest winter paintings at Moret-sur-Loing in the same years, provided a parallel exploration of frost and snow in the Seine basin that invites direct comparison with Monet's approach.

The frost-covered landscape is handled in a limited, restrained palette of pale grey, cool white, and faint warm ochre where weak winter light catches the surface. The paint is applied relatively thinly, capturing the crisp, delicate quality of frost rather than the impasted mass of snow. Horizontal composition emphasizes the flat, muted winter land.
