The gods were sure the leech was a mistake: an animal that somehow got out of hand. How well they had thought to the creation of lions and the like! But leech was clinging on to each as though it would solve his problem. The gods were in a fix. He was their creature.
Atlas holding up the earth developed DVT and somewhere a vein burst. He had his hands full so he asked the leech to do something about it. Of course he stanched the flow of blood and the vein closed itself as by magic. The gods who watched it were unimpressed, ”There is nothing to it. A beginner’s luck.” It was Hera who said, ”Just the same we shall keep him around. Accidents can happen.”
