Quotations
Ancient swords were frequently “flamboyant,” or with waved edges; more especially those used for purposes of state. The Dukes of Burgundy bore a two-handed sword of this form. Indeed, “flaming swords,” as they were called, were worn down to the times of our Charles II., and perhaps later.
