The jester is an elusive character. The European words used to denote him can now seem as nebulous as they are numerous, reflecting the mercurial man behind them: fool, buffoon, clown, jongleur, jogleor, joculator, sot, stultor, scurra, fou, fol, truhan, mimus, histrio, morio. He can be any of these, while the German word Narr is not so much a stem as the sturdy trunk of a tree efflorescent with fool vocabulary. The jester's quicksilver qualities are equally difficult to pin down, but nevertheless not beyond definition.
