Sergeant
RALPH: We now know that the battle is being fought between the forces of King Duncan and those of the nobleman Macdonald, who is rebelling against the king. Part of Macdonald’s forces consist of kerns and gallowglasses.
DAVINA: Kerns and gallowglasses are Celtic warriors from the Western Islands off the coast of Scotland. The Celts were the earliest inhabitants of Great Britain.
RALPH: However, waves of Germanic tribes arrived in Britain in the 5th Century and their Anglo-Saxon culture eventually dominated in England and the populated lowlands of Scotland. That left the more primitive Celts only in Wales, the remote Scottish Highlands, and the Western Islands.
DAVINA: King James, like all lowland Scots, tended to view the Celts as uncouth barbarians; so it’s not surprising that Shakespeare has characterized the kerns and gallowglasses as villains here.
