In Mahabalipuram near the Ganesh Ratha, you will be seeing a boulder on the slope of a hill which you will never notice on first sight, if there are no people around. But, when you watch closely, you will see that it’s a huge one, an approximate sphere balancing on the slope of the hill, around 5 metres in diameter and possibly weighing 250 tonnes, resting on a four square feet base. Is it a protruding part of the hill or someone placed it, no one knows but it is known to exist at least from the days of Narasimhavarman Mahamalla. This boulder, which goes by the name Krishna’s Butter Ball, is a popular tourist attraction in Mahabalipuram.
Originally, this was known as Vaan Irai Kal or Stone of The Sky God. The name Krishna’s butter ball was said to have been used for the first time in 1969 only. It is said that Narasimhavarman tried to get it moved but failed(after that he ordered none to touch the boulder) and may be many more, but the most recent attempt was that of Arthur Lawley who used seven elephants to pull the rock down. Well, it didn’t budge even an inch. It is also possible that this stone is a part of the original hill and was carved as like the rest of the places in the village. This rock was the inspiration to create the famous mud dolls called Thanjavur Bommai.
