Sir Lybius arms himself, and leaps on horseback: he finds two giants roasting a wild boar, who have a fair lady their captive. Sir Lybius, by favour of the night, runs one of them through with his spear: is assaulted by the other: a fierce battle ensues: he cuts off the giant's arm, and at length his head. The rescued lady (an Earl's daughter) tells him her story; and leads him to her father's castle; who entertains him with a great feast; and presents him at parting with a suit of armour and a steed. He sends the giant's head to K. Arthur.
Sir Lybius, maid Ellen, and the dwarf, renew their journey: they see a castle stuck round with human heads; and are informed it belongs to a knight called Sir Gefferon, who, in honour of his lemman or mistress, challenges all comers: He that can produce a fairer lady, is to be rewarded with a milk-white faulcon, but if overcome, to lose his head. Sir Lybius spends the night in the adjoining town: In the morning goes to challenge the faulcon. The knights exchange their gloves: they agree to just in the market place: the lady and maid Ellen are placed aloft in chairs: their dresses: the superior beauty of Sir Gefferon's mistress described: the ceremonies previous to the combat. They engage: the combat described at large: Sir Gefferon is incurably hurt; and carried home on his shield. Sir Lybius sends the faulcon to K. Arthur; and receives back a large present in florins. He stays 40 days to be cured of his wounds, which he spends in feasting with the neighbouring lords.
Sir Lybius proceeds for Sinadone: in the forest he meets a knight hunting, called Sir Otes de Lisle: maid Ellen charmed with a very beautiful dog, begs Sir Lybius to bestow him upon her: Sir Otes meets them, and claims his dog: is refused: being unarmed he rides to his castle, and summons his followers: they go in quest of Sir Lybius: a battle ensues: he is still victorious, and forces Sir Otes to follow the other conquered knights to K. Arthur.
Sir Lybius comes to a fair city and castle by a riverside, beset round with pavilions or tents: he is informed, in the castle is a beautiful lady besieged by a giant named Maugys, who keeps the bridge, and will let none pass without doing him homage: this Lybius refuses: a battle ensues: the giant described: the several incidents of the battle; which lasts a whole summer's day; the giant is wounded: put to flight; slain. The citizens come out in procession to meet their deliverer: the lady invites him into her castle: falls in love with him; and seduces him to her embraces. He forgets the princess of Sinadone, and stays with this bewitching lady a twelvemonth. This fair sorceress, like another Alcina, intoxicates him with all kinds of sensual pleasure; and detains him from the pursuit of honour.
