The Association of the Virgin Mary with the French Chess Piece “Dame”.
Today most chess historians agree that the weak chess queen, named “dame” in France as from the XIV century, changed to a powerful chess queen in Spain in 1475. Around this year we also see a change of the weak bishop to a strong bishop, according to the chess poem Scachs d’amor. In order to strengthen our hypothesis of Isabella I of Castile (Isabel la Católica) we have written a book about the new bishop and a book about Scachs d’amor in English.
Furtheron it is necessary to emphasize the complete study of Prof. Joaquín Petzold from Berlin affected in 1994 concerning the Virgin Mary, “Dame” and Isabella I of Castile in relation to the chessboard in Spain. Concentrating now on Virgin Mary in relationship with Isabella I of Castile we observe that the Augustinian monastic Martin de Córdoba wrote -in 1468 the work El Jardin de las donzellas. It was directed to Princess Isabel I of Castile with the intention to contribute to her education as future Queen. Cordoba was the first writer who draws equivalencies between Isabella I of Castile and Virgin Mary, which became one of her standard portrayals. Shorty thereafter we see the appearance of a new powerful chess queen.
