Of all the claims which have been advanced to the invention and origin of chess, that of the Hindu Game the Chaturanga is the most ancient, and its accounts contain the earliest allusion worthy of serious notice to anything partaking of the principles and form of chess. The description of it is taken from the Sanskrit text, and our first knowledge of it is obtained through the works of Dr. Hyde, 1693, and Sir William Jones, 1784, Professor Duncan Forbes in a History of Chess, dedicated to Sir Frederic Madden and Howard Staunton, published in 1860, further elaborated the researches of his predecessors and claims by the aid of his better acquaintance with chess, and improved knowledge of the Sanskrit to have proved the Chaturanga as the first form of chess beyond a shadow of doubt.
