Winter wonderlands and the original Christmas story
Leave the crowds behind and escape to a snowy street in Paris or learn how different artists have painted scenes of the Nativity through history:
Monet painted this Snow Scene at Argenteuil during the particularly snowy winter of 1874/5. Rather than focus on detail, Monet gives a sense of the atmosphere of an overcast afternoon with the sun slowly fading from the sky.
That same winter, fellow Impressionist Alfred Sisley painted this scene of The Watering Place at Mary-le-Roi. His rough brushwork suggests he painted it quickly, outdoors, in one sitting.
Almost 100 years earlier, Romantic painter Caspar David Friedrich also limited his range of pigments for his snowy Winter Landscape. He creates a shimmering translucent mist by carefully stippling with the point of a brush using smalt, a blue pigment that contains glass and is transparent in an oil medium.
