Krishna's Butterball is a gigantic natural granite boulder, roughly five metres across and estimated at hundreds of tonnes, that perches on a smooth sloping rock on the Mamallapuram hill yet has never rolled away. Its Tamil name, Vaan Irai Kal, translates roughly as the stone of the sky god, and it sits amid the Pallava monuments that make up the UNESCO ensemble.
By tradition the boulder is a dollop of butter dropped by the child-god Krishna, famous in legend for stealing butter, which gives the rock its popular English name. Whatever its origin, its gravity-defying balance has made it one of Mamallapuram's most photographed and best-loved sights.
