Georgic and Merlin is a French fairy tale collected by François Cadic in "La Paroisse bretonne".
One day, it pleaded with the lord's son Georgic, who freed it; it told him to call on it, Merlin, if in need and then flew off.
Then he called on the bird to give him a whistle to summon the wolves and muzzles to keep them from biting, and so he kept the sheep safe.
The third day, Georgic wore a purple cloak, and he stopped and borrowed a long iron fork that a man was using on the stove.
The daughter said the dragon slayer had cut out the tongues, and the coal miner claimed to have eaten them.
The lord held a great feast, and the daughter saw Georgic in his black cloak, which had exactly the hole in it that she had cut.
Then he would reach the Fountain of Life, but he should go to the Yellow Queen's castle first, taking some wine and bread, and a lance, calling out it was for his father-in-law's health.
He would then find a stag which he should ride to the Fountain; if the lion that guarded it woke, he should use the lance to kill it.
