Keeping the course of the river Nile, he soon arrived at the capital of Abyssinia, and rejoined Senapus. The joy of the king was great when he heard again the voice of the hero who had delivered him from the Harpies. Astolpho touched his eyes with the plant which he had brought from the terrestrial paradise, and restored their sight. The king's gratitude was unbounded. He begged him to name a reward, promising to grant it, whatever it might be. Astolpho asked an army to go to the assistance of Charlemagne, and the king not only granted him a hundred thousand men, but offered to lead them himself.
The night before the day appointed for the departure of the troops Astolpho mounted his winged horse, and directed his flight towards a mountain, whence the fierce South-wind issues, whose blast raises the sands of the Nubian desert, and whirls them onward in overwhelming clouds. The paladin, by the advice of St. John, had prepared himself with a leather bag, which he placed adroitly, with its mouth open, over the vent whence issues this terrible wind. At the first dawn of morning the wind rushed from its cavern to resume its daily course, and was caught in the bag, and securely tied up. Astolpho, delighted with his prize, returned to his army, placed himself at their head, and commenced his march. The Abyssinians traversed without danger or difficulty those vast fields of sand which separate their country from the kingdoms of Northern Africa, for the terrible South-wind, taken completely captive, had not force enough left to blow out a candle.
Senapus was distressed that he could not furnish any cavalry, for his country, rich in camels and elephants, was destitute of horses. This difficulty the saint had foreseen, and had taught Astolpho the means of remedying. He now put those means in operation. Having reached a place whence he beheld a vast plain and the sea, he chose from his troops those who appeared to be the best made and the most intelligent. These he caused to be arranged in squadrons at the foot of a lofty mountain which bordered the plain, and he himself mounted to the summit to carry into effect his great design. Here he found vast quantities of fragments of rock and pebbles. These he set rolling down the mountain's side, and, wonderful to relate, as they rolled they grew in size, made themselves bodies, legs, necks, and long faces. Next they began to neigh, to curvet, to scamper on all sides over the plain. Some were bay, some roan, some dapple, some chestnut. The troops at the foot of the mountain exerted themselves to catch these new-created horses, which they easily did, for the miracle had been so considerate as to provide all the horses with bridles and saddles. Astolpho thus suddenly found himself supplied with an excellent corps of cavalry, not fewer (as Archbishop Turpin asserts) than eighty thousand strong. With these troops Astolpho reduced all the country to subjection, and at last arrived before the walls of Agramant's capital city, Biserta, to which he laid siege.
We must now return to the camp of the Christians, which lay before Arles, to which city the Saracens had retired after being defeated in a night attack led on by Rinaldo. Agramant here received the tidings of the invasion of his country by a fresh enemy, the Abyssinians, and learned that Biserta was in danger of falling into their hands. He took counsel of his officers, and decided to send an embassy to Charles, proposing that the whole quarrel should be submitted to the combat of two warriors, one from each side, according to the issue of which it should be decided which party should pay tribute to the other, and the war should cease. Charlemagne, who had not heard of the favorable turn which affairs had taken in Africa, readily agreed to this proposal, and Rinaldo was selected on the part of the Christians to sustain the combat.
The Saracens selected Rogero for their champion. Rogero was still in the Saracen camp, kept there by honor alone, for his mind had been opened to the truth of the Christian faith by the arguments of Bradamante, and he had resolved to leave the party of the infidels on the first favorable opportunity, and to join the Christian side. But his honor forbade him to do this while his former friends were in distress; and thus he waited for what time might bring forth, when he was startled by the announcement that he had been selected to uphold the cause of the Saracens against the Christians, and that his foe was to be Rinaldo, the brother of Bradamante.
While Rogero was overwhelmed with this intelligence Bradamante on her side felt the deepest distress at hearing of the proposed combat. If Rogero should fall she felt that no other man living was worthy of her love; and if, on the other hand, Heaven should resolve to punish France by the death of her chosen champion, Bradamante would have to deplore her brother, so dear to her, and be no less completely severed from the object of her affections.
While the fair lady gave herself up to these sad thoughts, the sage enchantress, Melissa, suddenly appeared before her. "Fear not, my daughter," said she, "I shall find a way to interrupt this combat which so distresses you."
Meanwhile Rinaldo and Rogero prepared their weapons for the conflict. Rinaldo had the choice, and decided that it should be on foot, and with no weapons but the battle-axe and poniard. The place assigned was a plain between the camp of Charlemagne and the walls of Arles.
Hardly had the dawn announced the day appointed for this memorable combat, when heralds proceeded from both sides to mark the lists. Erelong the African troops were seen to advance from the city, Agramant at their head; his brilliant arms adorned in the Moorish fashion, his horse a bay, with a white star on his forehead. Rogero marched at his side, and some of the greatest warriors of the Saracen camp attended him, bearing the various parts of his armor and weapons. Charlemagne, on his part, proceeded from his intrenchments, ranged his troops in semicircle, and stood surrounded by his peers and paladins. Some of them bore portions of the armor of Rinaldo, the celebrated Ogier, the Dane, bearing the helmet which Rinaldo took from Mambrino. Duke Namo of Bavaria and Salomon of Bretagne bore two axes, of equal weight, prepared for the occasion.
The terms of the combat were then sworn to with the utmost solemnity by all parties. It was agreed that if from either part any attempt was made to interrupt the battle both combatants should turn their arms against the party which should be guilty of the interruption; and both monarchs assented to the condition that in such case the champion of the offending party should be discharged from his allegiance, and at liberty to transfer his arms to the other side.
