The tragic history of the royal house of Denmark opens with an episode which seems today, on any rational basis, absurd. Horatio tells Marcellus and Bernardo on the castle terrace at midnight that the elder Fortinbras, King of Norway, challenged Hamlet's father to single combat, agreeing to forfeit all his lands if vanquished, and that the Danish king put up an equal stake. In the ensuing encounter Fortinbras was slain. The elder Hamlet thus appears as a reckless champion, risking life and lands on personal valor, rather than as a careful guardian of his domain. Nowadays, if we give this a thought, we are likely to dismiss it as an odd custom, familiar from Viking days and the time when knighthood was in flower. It is indeed one of the archaic features of the old tale of Amleth which survived into Shakespeare's pages, but it still had, in the Elizabethan age, a validity which is not always realized. Although it is only a small piece in the great tapestry of Hamlet, it will repay, I think, some special examination.
