The art of wall paintings under the Sikhs flourished during the 18th century. These murals were basically used to decorate the shrines and houses.
Most of the Sikh murals are themed around the Sikh gurus, the popular ones being Guru Nanak and Guru Gobind Singh. These paintings depict their life and preachings. Guru Nanak is often portrayed in a meditative mood, accompanied by Bhai Mardana who is shown playing on the Rabab. Guru Gobind Singh is mostly shown riding on a horse, with a falcon in his hands and accompanied by a hound and some attendants. Following the gurus in popularity are the Sikh martyrs, who laid down their lives in the struggle against the Mughals. These soldiers are often depicted in the scene of a battlefield.
Since Sikhism does not promote idol worship, these paintings are not meant for worship. They only serve as a means of decoration.
