Look at the testimony of literature. In the days of chivalry our sympathies go with the Knight-errant, who redresses wrongs; with the King, whose courage and wisdom deliver his people from their enemies. But when Kingship became tyranny, and feudalism oppression, we took our heroes from the rebels. Robin Hood, Hereward the Wake, Bonnie Prince Charlie, Rob Roy; it was always the Under Dog that appealed to the artist.
