The Angelus Novus by Paul Klee is a monoprint, showing "an angel, contemplated and fixated on an object, slowly moving away from it", according to the purchaser of the piece of art, German philosopher Walter Benjamin.

According to several experts and philosophers, Paul Klee painted what is imagined to be the "Angel of History" by many. Klee was conscripted into the the German forces during World War One and was deeply affected by this.

Klee's method of "painting" the Angelus Novus was actually invented by the man himself. His oil transfer technique (monoprint) involved covering a piece of tracing paper with ink, then placing drawing paper underneath and scratching the top paper with a needle or another sharp object in order to to make a copy on the one below.

His "painting" shows an apparently "aghast" angel, eyes glued to an image of despair, stuck in a flying motion neither going forwards nor backwards. Not many paintings likes this one can be seen in the world, due to Klee's inventive new technique and also due to the topic of which Paul created his work.

According to Walter Benjamin: "A storm is blowing from Paradise; it has got caught in his wings with such violence the angel can no longer close them. This storm irresistibly propels him into the future to which his back is turned, while the pile of debris before him grows skyward. This storm is what we call progress."

Paul Klee's art style was "expressionism", a style which in it's simplicity portrays significant meaning. "Pierrot Lunaire" is arguably the most alike to the Angelus Novus. Another painter who gained a lot of fame for his expressionist style is Edvard Munch, who created the extremely famous painting "The Scream".
