Constantine, on his return, was of course very angry at having been so cleverly duped, and vainly tried to devise some plan for recovering the daughter whom he loved so well. When a magician came, therefore, and promised to execute his wishes, he gladly provided him with vessel and crew to sail to Bari. The magician, disguised as a peaceful merchant, spread out his wares as soon as he was anchored in port, and by a series of artful questions soon ascertained that Rother was absent, and that Oda was at home, carefully guarded by the principal nobles of the realm. When he also learned that one of these noblemen had a crippled child, the magician informed the people who visited his vessel to inspect his wares, that the most precious treasure in his possession was a magic stone, which, in a queen's hands, had the power of restoring cripples. The rumor of this miraculous stone reached the court, and the nobleman persuaded the kind-hearted queen to go down to the vessel to try the efficacy of the stone. As soon as Oda was on board, the vessel set sail, bearing her away from her husband and back to her father's home, where she was welcomed with great demonstrations of joy. Rother, coming back from the war shortly after her disappearance, immediately prepared a vessel to go in pursuit of her, selecting his giants and bravest noblemen to accompany him. Once more they landed at a short distance from Constantinople, and Rother bade his men hide in a thicket, while he went into the city, disguised as a pilgrim, and carrying under his robe a hunting horn, which he promised to sound should he at any time find himself in danger. He no sooner entered the city than he noticed with surprise that all the inhabitants seemed greatly depressed. He questioned them concerning their evident sadness, and learned that Imelot, having effected his escape from captivity, had invaded the kingdom, and vowed that he would not retreat unless Oda married his ugly and hunchbacked son that very day.
