Depending on which version of the Arthurian legend you read you may or may not agree, but one version says that Merlin repaired the hanging dance (Stonehenge) for the high king and then he died so was buried beneath it, to strengthen the Kingdom for the coming of Arthur. So "To speed the King, to feed the stones, to succour the land"

The greatest part of wisdom is learning to develop  the ineffable genius of extracting the "neither here nor there" out of any situation...."
