We have no means of ascertaining, says Forbes the exact era at which the Chaturanga passed into the Shatranj, or in other words at what period as the Muhammadans view it, the Hindus invented the latter form of the game. The earlier writers of Arabia and Persia do not agree on the point, some of them placing it as early as the time of Alexander the Great and others as late as that of Naushurawan. Even the poet Firdausi, the very best authority among them though he devotes a very long and a very romantic episode to the occasion of the invention of the Shatranj, is quite silent as to the exact period; all that he lets us know on that point is that it took place in the reign of a certain prince who ruled over northern India and whose name was Gau, the son of Jamhur. Sir William Jones was Judge of a Supreme Court of Judicature in Bengal, from 27 April, 1783 to 27 April, 1794, when he died at Calcutta. It is recorded that he came much in contact with intelligent Brahmans and was much esteemed. He states on the authority of his friend the Brahman "Radha Kant" "that this game is mentioned in the oldest (Hindu) law books; and that it was invented by the wife of Ravan, King of Lanka, the capital of Ceylon, in order to amuse him with an image of war while his metropolis was closely besieged by Rama in the second age of the world." NOTE. Sir William Jones says: If evidence be required to prove that chess was invented by the Hindus, we may be satisfied with the testimony of the Persians, who, though as much inclined as other nations to appropriate the ingenious inventions of a foreign people, unanimously agree that the game was imported from the west of India, together with the charming fables of Vishnusarma, in the Sixth century of our era. It seems to have been immemorially known in Hindustan by the name of Chaturanga, that is the four "angas" or members of an army, which are said in the Amarakosha to be Hasty-aswa-ratha-padatum, or Elephants, Horses, Chariots and Foot Soldiers, and in this sense the word is frequently used by epic poets in their descriptions of real armies. By a natural corruption of the pure Sanskrit word, it was changed by the old Persians into Chatrang; but the Arabs, who soon after took possession of their country, had neither the initial or final letter of that word in their alphabet, and consequently altered it further into Shatranj, which found its way presently into the modern Persian, and at length into the dialects of India, where the true derivation of the name is known only to the learned. Thus has a very significant word in the sacred language of the Brahmans been transferred by successive changes into axedres, scacchi, echecs, chess and by a whimsical concurrence of circumstances given birth to the English word check, and even a name to the Exchequer of Great Britain!
