It is known that the game of chess originated in India. It was passed on to the medieval West through the intermediary of the Persians and the Arabs, a fact to which we owe, for example, the expression "check-mate", (German: Schachmatt) which is derived from the Persianshah: "king" and the Arabic mat: "he is dead".

In the original position of the chessmen, the ancient strategic model remains obvious; one can recognize the two armies ranged according to the battle order which was customary in the ancient East: the light troops, represented by the pawns, form the first line ; the bulk of the army consists of the heavy troops, the war chariots ("castles"), the knights ("cavalry") and the war elephants ("bishops"); the "king" with his "lady" or "counsellor" is positioned at the centre of his troops.
The form of the chess-board corresponds to the "classical" type of Vāstu-mandala, the diagram which also constitutes the basic layout of a temple or a city. It has been pointed out that this diagram symbolizes existence conceived as a "field of action" of the divine powers. The combat which takes place in the game of chess thus represents, in its most universal meaning, the combat of the devas with the asuras, of the "gods" with the "titans", or of the “angels” with the "demons", all other meanings of the game deriving from this one.
The most ancient description of the game of chess which we possess appears in "The Golden Prairies" by the Arab historian al-Mas‘ūdī, who lived in Bagdad in the 9th century. Al-Mas‘ūdī attributes the invention—or codification—of the game to a Hindu king "Balhit", a descendant of
