« The King (James the Conqueror) entered the city of Montpellier on Thursday the 2nd of June of the year 1239; and on the next day, Friday, between midday and the ninth hour, the King writes that the Sun was eclipsed in a way people did not remember ever having seen before, because it was entirely covered by the Moon and the day grew so dark that one could see stars in the sky. » d'après : Zurita, Anales de la Corona de Aragon.
