The battle is historical, recorded in medieval chronicles, but the details of Macbeth's death and the cairn's link to him are traditional. Shakespeare's Macbeth, first performed around 1606, is a fictional drama and moves the final battle to Dunsinane.
The Peel Ring is unrelated to Macbeth in date. The legend is included here because the cairn is a point of local tradition, not because any supernatural event is claimed.
