reference to Chess is in the Sanskrit prose romance
The first reference to Chess is contained in the Sanskrit prose romance,
The Vasavadatta and follows in the footsteps of the epic stories contained in the Mahabharata, Ramayana, Bhagavad Gita, the Grecian Iliad and the Odyssey.
By the 6th century AD, Chaturanga (the precursor of Chatrang, Shatranj and traditional Chess) was being played in India. This game migrated to Europe via Persia and Spain about four centuries later.
In India the pieces represented divisions of the Kings army. Elephants, cavalry, chariots and foot-soldiers were led into battle by
his majestic beneficence and his Vizier.
The Vizier was to become a Queen in the European version of the game and in the course of history the Indian elephant has metamorphosised into our Bishop - the chariot into our Rook.
