Stories involving lost items, sick or missing birds and animals, and the strange behaviour of objects such as coins, candles and relic containers are frequently encountered in high medieval miracle collections, with the 'jokes' of St Foy of Conques being a well-known example. Such miracles, in which saints were thought to incongruously exercise their powers on 'minor' or 'trifling' matters, provoked a range of reactions, from laughing delight to unease and outright dismissal. This essay argues that the 'trifling' miracle would be a useful addition to typologies of medieval miracles, and contrasts the ways in which two late twelfth-century monks at Canterbury, Benedict of Peterborough and William of Canterbury, worked to integrate and explain stories like these in their collections of the miracles of Thomas Becket.
