Alfonsine codice, astronomy, medieval Spain
The fame of Alfonso X, il Sabio, 1221-1284, rests principally upon the voluminous literary production of his Royal Scriptorium. Many of the original Alfonsine codices survive today and can be found in the libraries of England, France, Italy, and, of course, Spain.
