King of Mabon Rock. He was besieged by a king named Vadalon, but Agrippe's daughter poisoned the water supply used by the besiegers, and they were forced to abandon the assault. In revenge, Vadalon imprisoned Agrippe's daughter in iron bands, from which she was eventually released by Sir Bors.
Uncle of King Rions (Ryons), Arthur's enemy. He invaded the Waste Land, owned by Perceval's mother, and killed fourteen of the lady's sons. Aglovale, one of the surviving sons, raised an army of Arthur's knights, encountered Agrippe's forces, and finally killed Agrippe.
Agrippes Daughter, King
King Vadalon was besieging King Agrippe. (If the translation is correct, Vadalon claimed Agrippe had killed Vadalon's brother, the King of Norgales.) Food ran short and all the wells except one supplying the besiegers were dried up. King Agrippe's daughter poured strong poison into this last well, killing 5.000 besiegers and forcing the others to return to their own country. Vadalon had the princess tracked and seized. Thinking death too lenient, he had two iron bands fixed so tightly round her body that they cut skin in several places.
She defied Vadalon, telling him she would find a deliverer, but would let no one remove the bands unless he also swore to avenge her. Vadalon, she said, would recognize her avenger because he would carry the shield of Vadalon's brother, whom Agrippe was said to have killed.
The princess, who could travel only in easy stages, was on her way with a few companions to Arthur's court to find a champion when Sir Bors found her resting in her pavilion. Swearing to bear the shield in question for a year and a day to punish Vadalon, Bors gently broke her bands with his bare hands.
Agrippe the Tall
A count or earl whose lands bordered on those of King Hoel of Brittany. Agrippe waged war on Hoel, besieging the town of Alinge and wounding Kahedin, Hoel's son. On the verge of defeat, Hoel enlisted the aid of Tristan, who subsequently killed Agrippe's nephew, Alquin, and spurred Hoel's forces to victory. Agrippe was slain in the battle.
The same character is known as Albroino in the Italian La Tavola Ritonda.
