Lukes Iron Crown.
George and Luke Dosa headed an unsuccessful revolt against the Hungarian nobles in the early part of the sixteenth century. Luke (according to Goldsmith) underwent the torture of the red-hot iron crown, as a punishment for allowing himself to be proclaimed king. History says it was George, not Luke. (The Traveller.)
