El ajedrez de la dama — the recasting of chess in late fifteenth-century Spain and Lucena's Salamanca book

The game the world plays is not the game that came out of India and Persia. In the last quarter of the fifteenth century the queen and the bishop were given the long moves they still have, and the earliest printed book on the result was written by a student at Salamanca and dated by a dedication to a prince who died in October 1497. Its author had no name for the new game but "de la Dama", and explained its moves by their difference from "el viejo".
