India and Iran: Works on Paper at the London-based, Oliver Forge & Brendan Lynch Ltd., includes a striking image of the Hindu God Vishnu as Venkateshvara, dated to the late 18th century. This gouache heightened with gold on paper, depicts the four-armed Hindu god Vishnu in his human avatar as Venkateshvara or forgiver of sins. It was painted in Andhra Pradesh in south India, probably at Tirupati, north-west of Madras (Chennai), where a school of painting flourished in the eighteenth century. The style of painting, with lavish use of gold, is distinctly south Indian.
