Bayart in the sagas of the Middle Ages, was the famous horse of the four Heimon children, on which they all sat, and whose fleetness, courage, and strength made them so dangerous to the king of France, that the forgiveness of four of their atrocious deeds was conditioned on the sacrifice of this noble steed. The oldest son, Renaud, was obliged to tie a millstone to the horse's neck. and throw it into the Seine; but it worked its way lup again and swam to the shore. The weight was doubled and redoubled, but every time it gained new power and courage when it saw its rider. At last a millstone was tied to each foot, and around the neck, and Renaud was ordered away. The noble animal again came out of the water, but, not seeing its master, lost its strength and sank.
