Students at the University of St Andrew's risk facing bad luck and possible exam failure if they step on the initials of Patrick Hamilton marked in the cobbles outside St Salvator’s Quad. Hamilton was a student and Protestant martyr who was burned alive at the stake outside the college in 1528. Tradition holds that the only way to break the curse of accidentally treading on the stone is to run backwards three times around the quad at the change of class, naked. Fortunately an alternative way of cleansing exists in the form of the May Dip, when students gather on the beach to run into the North Sea at sunrise. Once exams finish in the summer, students jump on Hamilton’s initials to celebrate.
