Arvegagus and his lady, Dorigen, were so in love with each other that even the shortest parting brought great heartache. While Arvegagus was away on a mission for the king, Dorigen collapsed into a great depression, fearing the worst. She would sit on the cliff's edge imagining her beloved shipwrecked amongst the deadly rocks, never to return to her loving arms.
A squire named Aurelius sat down beside the grieving lady. He quickly announced he longed for her. Without pausing, Daoigen, with a snarl in her voice, told the young squire she would never betray her husband with such a dishonorable act as taking another.
Attempting to manipulate his offer, she told him she would welcome him to her chamber and lay in his embrace if he could rid the coast of Brittany of its jagged and treacherous rocks to allow her husband a safe return.
His desire for Dorigen was so great he turned to an astrologer, a master of wizardry. He offered him great riches to create an illusion to make the deadly rock disappear for one week.
The wizard an expert in the power of star magic calculated the conjunction of the planets to grant the squire's wish. He stood arms high over his head and commanded the fog move out to the sea, the rocks flatten to the sand floor and the water to become smooth and calm.
When Dorigen, reached the cliffs to sit and pine she saw the jagged rocks were no more. With her head in her hands she cried for the safe return of her husband and in horror over the promise made to the young squire.
Arvegagus returned from his voyage. His bride fell to her knees at the feet of her beloved. She cried uncontrollably as she declared the promise she made to Aurelius. Her husband told her the foundation of their union was honesty, and she must keep her word to the squire with no fear of losing him for the deed would be forgiven. He would accept her back into his heart.
Aurelius, learning that Dorigen's husband would accept her back free of prosecution was moved by his nobility, released his claim on her. The astrologer, not wishing to be outdone by chivalry, requested no riches from the squire for his part in the deed.
