The brahmin Sissa ibn Dahir (also called Sessa or Sassa) is a mythical character from India, known for the invention of Chaturanga, the Indian predecessor of chess, and the Wheat and Chessboard Problem he would have presented to the king when he was asked what reward he'd like for that invention.[1]

A legend of the invention of chessEdit


Sissa invents chess for an Indian king for educational purposes. In gratitude, the King asks Sissa how he wants to be rewarded. Sissa wishes to receive an amount of grain which is the sum of one grain on the first square of the chess board, and which is then doubled on every following square.[2]

This request is now known as the Wheat and Chessboard Problem, and forms the basis of various mathematical and philosophical questions.

Historical originEdit

Until the nineteenth century, the legend of Sissa was one of several theories about the origin of chess. Today it is mainly regarded as a myth because there is no clear picture of the origin of chaturanga (an ancient Indian chess game), and from which modern chess has developed.

The context of the mythical Sissa is described in detail in A History of Chess. There are many variations and inconsistencies, and therefore little can be confirmed historically. Nevertheless, the legend of Sissa is placed by most sources in a Hindu kingdom between 400 and 600 AD, in an era after the invasion of Alexander the Great. The myth is often told from a Persian and Islamic perspective.[3]

However, the oldest known narrative believed to have been the basis for the legend of Sissa is from before the Islam. It tells of Husiya, daughter of Balhait, a queen whose son is killed by a rebel, but of whom she does not initially hear the news. This news is subtly announced to her through the chess game that Sissa introduced to her.[4]
