This is a town where Chagall has been born. The Russian intellectuals (especially Jewish) have supported the revolution(the cock standing(basing) on yellow(Jewish) houses). The revolution had tried to resolve deep social problems in the Russian society. Thus the cock is white and have inclined toward a white sun. The new social experiments have been reflected in the art. It had given start to the huge number of avant-garde artists.This is represented by a big house in the foreground with red roof. But after the revolution had gotten on its own feet, it had turned against the intellectuals who had fed it.The revolutionary red roof had turned into a fire red. The artist had fled the country (they are fleeing because they are leaving through a window). The new ideas they took with them(the reddish hues of the human figure).
