Chess

Well, here's an interesting bit of information.  It seems Isabella the Catholic had a major influence on the rules of chess.  Originally the queen was not only not the key piece in the game but wasn't even the queen.  I suppose I thought, insofar as I thought about it at all, that the rules of chess came fully formed from the mind of God into the hands of . . . um, well I guess Adam.  It could fill in the hours when he wasn't earning his bread by the sweat of his brow.

In any event, Mrs Vidal gives you the whole story here.
