As long ago as 400 BC, the ancient Greeks were describing the medicinal properties of unicorns. This image of the killing and skinning of the pirassoipi, a twin-horned unicorn, is found in a study by Ambroise Paré, surgeon to the French Crown. Responding to questions from a persistent patient, Paré admitted that he was unconvinced of the unicorn’s medicinal effectiveness. The hunters in this scene have a cruel appearance. As Firenze told Harry in The Philosopher’s Stone, ‘it is a monstrous thing to slay a unicorn’. Shown here: ff. 18r
