And while we're dancing naked to honor spring, let us not forget that venerable and happy Druidic convention of threefold death!
In Welsh legend, Myrddin Wyllt (one of the sources for Merlin of Arthurian legend) is associated with threefold death. As a test of his skill, Merlin is asked to prophesy how a boy will die. He says the boy will fall from a rock. The same boy, with a change of clothes, is presented again, and Merlin prophesies that he will hang. Then, dressed in a girl's clothes, the boy is presented, and Merlin replies, "Woman or no, he will drown." As a young man, the victim, in a hunt, falls from a rock, is caught in a tree, and hanging head down in a lake, drowns.
Myrddin Wyllt also reportedly prophesied his own death, which would happen by falling, stabbing, and drowning. This was fulfilled when a gang of jeering shepherds drove him off a cliff, where he was impaled on a stake left by fishermen, and died with his head below water.
