 However, Gambra disagrees and believes that there are no reliable sources to support this assertion.The alleged repudiation appears only in a volume of "L'art de vérifier les dates" and, according to Gambra, "it is impossible, in the absence of better references, to grant credit to the assertion of Agnes' repudiation".In addition, he indicates that Lucas de Tuy, in his "Chronicon mundi", indicates that the Queen was buried in Sahagún.
