In Shakespeare’s play, Macbeth, the three witches that give the Ides of March prophesy live in Birnam Wood, a famed forest throughout Medieval and Renaissance Scotland. The only tree left today of that once vast forest is a sessile oak, nicknamed the Birnam Oak. It is several hundred years old and may have been a baby in Shakespeare’s time.
