Fairytale of the 7 running horses Painting

Did you know that there was once a water fall in the island of Avalon. The fall was magical anyone could come and go one side to other and never get wet. Merlin had cast a spell on that fall. When King Arthur died he threw away the Excalibur in the lake which Nimue hid forever. That was the day when she released the horses from the waterfall and later the fall disappeared. Some say it still exists but not known to anyone. The horses were set free thery were the colors of rainbow each for a different sign of abundance prosperity vitality etc. In this painting it's the moment of creation of the horses is all we see.
