Yes. Prof Drayson wrote in Asiatic Researches
The Hindus thought proper to connect their Mythology with an astronomcial period of a strange nature.
It is that of the Seven Rishies ( Ursa Major ) moing along the Zodiac in a retrograde motion of 2700 years,
This constellations takes 100 years to stay in a star and since the Zodiac is made up of 27 stars, it tkes 27*100 = 2700 years to make a retrograde circuit of the Great Heavenly Circle.
