Coimbra was one of the new conquests, and in that city Rodrigo was knighted. The ceremony was performed in the church of Saint Mary, which had once been the great mosque of Coimbra. The King girded on the sword and gave him the kiss, but not the blow, for the Cid needed no remembrancer of his duties. The ladies were his honourable attendants on this august occasion. The Queen gave him his horse, and the Infanta, Donna Urraca, fastened on his spurs. His names, Rodrigo Diaz, were now compressed into Ruydiez, agreeably to a frequent custom at investiture, which in so many respects was similar to baptism. By permission of the King he then exercised the privileges of his new rank by knighting nine noble squires. By this time the vow of the Cid was performed, and he retired awhile from the court to the society of his wife. [Sidenote: Death of King Ferdinand.] [Sidenote: The Cid becomes the knight of Sancho, King of Castile.] Ferdinand soon afterwards died, having, contrary to the principles of the nation's constitution, divided his kingdom among his children. This breaking up the interests of the Gothic monarchy was most unwise; for the Goths were a fierce race, and in the cause of ambition brother had shed brother's blood.[186] The Cid went into the service of Don Sancho, King of Castile, the eldest son of the late sovereign; and in all his wars, whether with Christians or Musulmans, he deported himself after his wonted manner: and his great feats of arms won so entirely the heart of the King that he made him his campeador, or officer whose duty it was to mark the place for the encampment of the host. [Sidenote: Mixture of evil and good in the Cid's character.] [Sidenote: Supports the King in his injustice.] Sancho expressed his purpose of possessing himself of what he chose to consider his inheritance,--the whole kingdom of his late father. His iniquitous design was manfully opposed by one of his counsellors, who nobly declared that there was not a man in the world who would advise him to break the command of his father, and the vow which he had made to him. Sancho then turned to the Cid, stating to him, singularly enough, that he solicited his advice, for his father had charged him upon pain of his curse not to act without his judgment. The Cid replied, that it would ill behove him to counsel his sovereign to contradict the will of the late King. Sancho rejoined, with admirable casuistry, that he did not think he was breaking his oath to his father, for he had always denied the justice of the partition, and the oath alluded to had been forcibly extorted. The Cid found the King was resolute in his purpose; and in the conflict of duties which the circumstances gave rise to, his martial spirit overcame his virtue, and he determined to continue his soldier.
