The King of Denmark, in fact, was at this time occupied with new loves. Ogier's mother having died, he had married a second wife, and had a son named Guyon. The new queen had absolute power over her husband, and fearing that, if he should see Ogier again, he would give him the preference over Guyon, she had adroitly persuaded him to delay rendering his homage to Charlemagne, till now four years had passed away since the last renewal of that ceremony. Charlemagne, irritated at this delinquency, drew closer the bonds of Ogier's captivity until he should receive a response from the king of Denmark to a fresh summons which he caused to be sent to him. The answer of Geoffroy was insulting and defiant, and the rage of Charlemagne was roused in the highest degree. He was at first disposed to wreak his vengeance upon Ogier, his hostage; but at the entreaties of Duke Namo, who felt towards his pupil like a father, consented to spare his life, if Ogier would swear fidelity to him as his liege-lord, and promise not to quit his court without his permission. Ogier accepted these terms, and was allowed to retain all the freedom he had before enjoyed. The Emperor would have immediately taken arms to reduce his disobedient vassal, if he had not been called off in another direction by a message from Pope Leo, imploring his assistance. The Saracens had landed in the neighborhood of Rome, occupied Mount Janiculum, and prepared to pass the Tiber and carry fire and sword to the capital of the Christian world. Charlemagne hesitated not to yield to the entreaties of the Pope. He speedily assembled an army, crossed the Alps, traversed Italy, and arrived at Spoleto, a strong place to which the Pope had retired. Leo, at the head of his Cardinals, advanced to meet him, and rendered him homage, as to the son of Pepin, the illustrious protector of the Holy See, coming, as his father had done, to defend it in the hour of need. Charlemagne stopped but two days at Spoleto, and learning that the Infidels, having rendered themselves masters of Rome, were besieging the Capitol, which could not long hold out against them, marched promptly to attack them. The advanced posts of the army were commanded by Duke Namo, on whom Ogier waited as his squire. He did not yet bear arms, not having received the order of knighthood. The Oriflamme, the royal standard, was borne by a knight named Alory, who showed himself unworthy of the honor.
