In this lithograph, published in 1937/38 in Verve art magazine, a woman is having a winter sleep. In her body, a little red heart stands out – maybe suggesting that she is bearing a baby. Just like the winter landscape (with which she seems to merge), the woman almost seems to hibernate. Once again, sleep is the place where life renews itself. Paul Klee was born in Germany in 1940. His work, although moulded by cubism, expressionism and surrealism, was greatly influenced by a trip to Tunis, where Klee reconceived his entire notion of light and colour.
