Documentary painting through portraiture

Answer: Documentary painting through portraiture

Under Maharaja Jaswant Singh's patronage, a trend for documentary painting through portraiture and depiction of court life started around 1640.

A productive period of painting was ushered in by Maharaja Jaswant Singh (1638–1678) in the mid–seventeenth century. A trend for documentary painting through portraiture and depiction of court life started under his patronage around 1640 and enjoyed prominence till the advent of photography in the nineteenth century when it substituted painting for recording events. Numerous portraits of Jaswant Singh survive. Due to his inclination towards the Vallabha cult of Shrinathji, he patronised many Krishna related themes with Bhagvata Purana as the most prominent one.
