shown in the affair which first revealed the unbending character of the future Cardinal Ximenes. During his youthful sojourn in Rome Ximenes procured papal "expectative letters" granting him the first preferment that should fall vacant in the diocese of Toledo. On his return he made use of these letters to take possession of the _arciprestazgo_ of Uceda, but it happened that Archbishop Carrillo simultaneously gave it to one of his creatures and, as Ximenes refused to surrender his rights, he was thrown into a tower in Uceda--a tower he subsequently, when himself Archbishop of Toledo, used as a treasury. As he continued obstinate, Carrillo transferred him to the Pozo de Santorcas, a harsh dungeon used for clerical malefactors, where he lay for six years, resolutely refusing to abandon his claim, until released at the intercession of the wife of a nephew of Carrillo.[34] Evidently the Castilian prelates had slender respect for papal diplomas. About the same time, during the civil war between Henry IV and his brother Alfonso, when Hernando de Luxan, Bishop of Sigüenza, died, the dean, Diego López, obtained possession of the castles and the treasure of the see, joined the party of Alfonso, and, with the aid of Archbishop Carrillo, caused himself to be elected bishop. Meanwhile Paul II gave the see to Juan de Maella, Cardinal-bishop of Zamora, but Diego López refused to obey the bulls and appealed to the future council against the pope and all his censures. He disregarded an interdict launched against him and was supported by all his clergy. Maella died and Paul II gave the bishopric to the Bishop of Calahorra, requesting Henry IV to place him in possession. So secure did Diego López feel that he rejected a compromise offering him the see of Zamora in exchange, but the possession of Sigüenza happened to be of importance in the war; by bribery a troop of royalist soldiers obtained admittance to the castle and carried off López as a prisoner.[35]
