One day Lisuarte, going to the chase with the Queen and his daughters, came to the mountain where the hermit Nasciano dwelt, and encountering Esplandian, resolved to adopt him, and the hermit showed him a letter, written by Urganda, which had been tied to Esplandian's neck when Nasciano found him. The letter was addressed to King Lisuarte himself, and advised him to cherish the boy, who one day would deliver him from the greatest danger. So Lisuarte resolved to attach Esplandian, and Sargil, his foster-brother, to his service. And when the hermit told how he had rescued Esplandian from the lioness Oriana knew him to be none other than her own son, for she had heard that the infant left on the threshold of the nunnery had been seized by a wild beast and carried off. In the course of his adventures, which were numerous and stirring, Amadis was sorely wounded by a monster which he had slain, and was cured of his hurt by a certain lady called Grasinda, to whom he was grateful for her kindness and assistance, and he promised to do her will in any adventure she might choose for him. About the same time El Patin, Emperor of Rome, resolved to ask King Lisuarte for the hand of Oriana. Hearing this, Queen Sardamira of Sardinia, who loved El Patin, came to Britain along with the ambassadors of the Roman Emperor, and, meeting Oriana, gave her some account of Amadis, telling her how on one occasion he had conquered El Patin in battle and how that emperor owed him a mortal grudge. Galaor, who suspected the love of Amadis and Oriana, went to Lisuarte, strongly advising him not to give Oriana in marriage to the Emperor, and set out for Gaul, hoping to receive some news of Amadis. At the same time Florestan betook himself to the Firm Island, to acquaint Agrayes of the troubles besetting Oriana, and to carry him news of his lady Mabilia, who longed to see him once more. 'The Greek Knight' But, as fortune would have it, Amadis, now calling himself 'the Greek Knight,' accompanied by the lady Grasinda, arrived in Britain. Amadis, desiring to remain incognito, gave explicit orders to all in his train not to divulge his name. He learned that Oriana was about to be given to the Emperor, and resolved to take his measures accordingly. Grasinda, however, mindful of his vow to her to embark in any adventure she might choose for him, sent a letter to King Lisuarte stating that she held herself fairer than any lady at his Court, and that did any knight deny this he must do battle with her champion, the Greek Knight. The Roman ambassadors requested of Lisuarte that they might be permitted to take up the challenge, and to this he acceded.
