In Moscow he was offered a job as stage designer for the newly formed State Jewish Chamber Theater. It was set to begin operation in early 1921 with a number of plays by Sholem Aleichem. For its opening he created a number of large background murals using techniques he learned from Bakst, his early teacher. One of the main murals was tall by long and included images of various lively subjects such as dancers, fiddlers, acrobats, and farm animals. One critic at the time called it "Hebrew jazz in paint". Chagall created it as a "storehouse of symbols and devices", notes Lewis. The murals "constituted a landmark" in the history of the theatre, and were forerunners of his later large-scale works, including murals for the New York Metropolitan Opera and the Paris Opera.
