says:-
(Before that, the queen moved 1 square diagonally, and that was its only move; and the bishop moved 2 squares (no more or less) but could jump.)The queen and bishop remained relatively weak until between 1475 AD and 1500 AD, in either Spain, Portugal, France or Italy, the queen's and bishop's modern moves started and spread
Has any more detailed information come to light about when and where the modern moves of queen and bishop started and spread?
(Before this, in some areas, the queen in its first move could move 2 squares to a square the same color, with jump :: this was one of various special first moves to make the game start quicker.)
