Editing Cox–Forbes theory (section)

==Theory==
The theory arose from an article by Hiram Cox published posthumously in ''Asiatic Researches'' in 1801. Cox's article was a commentary on an earlier article written by [[William Jones (philologist)|Sir William Jones]], which included an account of the [[India]]n text ''[[Bhavishya Purana]]'', which he believed to date from c.3000 BC. Jones stated that this contained a description of a four-player version of chess, presented in the form of a dialogue between [[Yudhishthira]] and [[Vyasa]].<ref>Jones, William, "On the Indian Game of Chess", ''Asiatick Researches'', Volume 2, 1798, p.160.</ref> Jones argued that the four-player version described was a variation of the original two-player form of the game. Cox's article, "On the Burmha Game of Chess Compared to the Indian", proposed that the four-handed version of the game was the earliest form of chess. He states that this version "is mentioned in  the oldest law books and is said to have been invented by the wife of Ravan",<ref name = "hir">Cox, Hiram, "On the Burmha Game of Chess Compared to the Indian", ''Asiatic Researches'', 1801, p.483.</ref> referring to [[Ravana]], the legendary king of Sri Lanka. Cox dates Ravan to "three thousand eight hundred years ago".<ref name = "hir"/>

Forbes developed this idea in his 1860 book ''The History of Chess'', accepting the 3000 BC dating of the Purana.<ref>Henry A. Davidson, ''A Short History of Chess'', Greenberg, 1949, Chapter 9.</ref><ref name = "part"/> In Forbes's explanation, the four-handed dice version is called ''Chaturanga'', and Forbes insists that ''Chaturaji'' is a misnomer that actually refers to a victory condition in the game akin to [[checkmate]].  In his 1860 account, the players in opposite corners are allies against the other team of two. He represents this "Chaturanga" as gradually developing into the two-player diceless form by the time it was adopted by the Persians as "Chatrang".  He further asserts that this name later became "[[Shatranj]]" after the Arabic pronunciation.
