Mural

Rather than making paintings around well-known epics like Ramayana and Mahabharata, Benode Behari Mukherjee was drawn to the lives of medieval saints. On the walls of Hindi Bhavana in Shantiniketan, he made a mural called Medieval Saints, in which he charts a history of medieval India through the lives of Tulsi Das, Kabir and others, and focuses on their humane teachings.
