A new exhibit — Chagall between War and Peace at Paris’ Musee de Luxembourg — attempts to show Marc Chagall as a historian of the 20th century. Through rich, colorful allegories of the two world wars, the Russian Revolution and his experience as a Jew fleeing Nazi Europe, Chagall’s paintings are presented as a witness account of the turbulent 20th century. Images of pogroms, Russian soldiers, war and Jewish persecution are juxtaposed with Judeo-Christian iconography. Chagall was born in Russia in 1887, traveled widely and died in France in 1985. It runs through July 21.
