There was a King in Greece married to the sister of the Emperor of Constantinople, by whom he had two fair sons, especially the elder, named Apolidon, who in his days had no equal for strength of body and courage of heart. He having a subtle genius, which is so seldom found with valour, gave himself to the study of the sciences and of all arts, so that he shone among those of his own time like the Moon among the stars; especially he excelled in necromancy, whereby things that appear impossible are done. The King his father was very rich in treasure, but poor in life, by reason of his great age; and seeing himself at the point of death, he commanded that the kingdom should be given to Apolidon, as his eldest son, and his books and treasures to the other. The younger was not contented with this, and told his father so with tears, and complained that he was disherited; but the old man, not knowing what to do, wrung his hands for pure sorrow. Then that famous Apolidon, seeing his father's grief and the littleness of his brother, bade him take comfort, for he would accept the books and treasure, and relinquish the kingdom to his brother. Whereat the father gave him his blessing with many tears. So Apolidon took his inheritance, and fitted out certain ships, manning them with chosen Knights, and set forth into the sea, trusting himself to Fortune, who seeing his great obedience to his father, and how he had thrown himself upon her mercy, resolved to requite him with glory and greatness. A fair wind carried him to the empire of Rome, where Siudan was then Emperor, at whose court he abode some time, doing great feats in arms, till there grew a true affection between him and the Emperor's sister, Grimanesa, who then flourished among all other women for beauty. So it was that as he was loving, even so was he loved, and as their loves might no other ways be indulged, they left Rome together, and set sail in Apolidon's fleet, and sailed till they came to the Firm Island. There Apolidon landed, not knowing what country it was, and pitched a tent upon the shore, and placed a couch there for his Lady, who was weary of the sea. Presently there came down a fierce Giant, who was Lord of the island, with whom, according to the custom of the place, Apolidon was to do battle for the preservation of his Lady and himself, and his company. It ended in such sort that the Giant lay dead on the field, and Apolidon remained master of the island. When he had seen its strength, he neither feared the Emperor of Rome, whom he had offended, nor all the world besides; and there he and Grimanesa, being greatly beloved by the islanders, whom he had delivered from their oppressor, dwelt in all happiness for sixteen years. During that time many rich edifices were made, as well with his great treasures, as with his surpassing wisdom, such as it would have been difficult for any Emperor or King, how rich soever, to have completed.
