text_original: In astronomy he corrected some of the errors in the old calculations and helped to explain the movements of the stars ; ballads he wrote of some merit and chronicles also ; but the chief work of his life was the Siete Partidas (seven divisions), a very comprehensive code of law compiled from the Roman and Visigothic rules, THE SPANISH PENINSULA 245 from the old local customs or fueros, and from the de  crees of various great Councils.
