Training of Isabella I of Castile as the Virgin Mary by Churchman Martin De Cordoba in 1468 - Govert Westerveld - Bog

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.
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.
