or CASQUE, a piece of defensive armour wherewith to cover the head and neck; otherwise called the head-piece and helmet*. The word is French, *See Helasque, from cassicum or cassicus, a diminutive of cassis met. "a helmet." Le Gendre observes, that anciently, in France, the gens d'armes all wore casks. The king wore a cask gilt; the dukes and counts silvered; gentlemen of extraction polished steel; and the rest plain iron.

The cask is frequently seen on ancient medals, where we may observe great varieties in the form and fashion thereof; as the Greek fashion, the Roman fashion, &c. F. Joubert makes it the most ancient of all the coverings of the head, as well as the most universal. Kings, emperors, and even gods themselves, are seen therewith. That which covers the head of Rome has usually two wings like those of Mercury; and that of some kings is furnished with horns like those of Jupiter Ammon; and sometimes barely bulls or rams horns, to express uncommon force.
