The 14th century's Bohemian illuminated manuscripts were created mainly at two major atelieurs: 1-the court one, working at the court of Charles IV and at the directly connected court of Wenceslas IV; and 2- at the more qualitatively stratificated atelieur of Prague's archepiscopate. Besides their mutual influences, the illuminations reveal different sources, either from the point of view of style or iconography.
