brought to England in the reign of Edward III., when John of Gaunt returned from Spain. In the dance, bells were jingled, and staves or swords clashed. It was a military dance of the Moors or Moriscos, in which five men and a boy engaged; the boy wore a morione or head-piece, and was called Mad Morion.
(See Maid Marian.)
