This chapter seeks to provide an explanation for the earliest Insular cult of St Katherine of Alexandria, which grew in popularity despite the absence of primary relics or an Insular pilgrimage site. Knowledge of St Katherine likely arrived in England prior to 1066, but her cult achieved widespread appeal following the Norman Conquest. This chapter proposes that this appeal was rooted in the congruencies between aspects of St Katherine’s character, which can be conceived of as generally ‘civilised’, and descriptions of ‘Englishness’ that rested on a conception of a cultural, rather than biological, national community. These depictions are evident in the circulating historical chronicles written during the twelfth century, which amalgamated English and Norman identities and differentiated the ‘English’ nation from its ‘barbarous’ neighbours. These same characteristics find expression in the vita of St Katherine and were highlighted liturgically, through music and text, testifying to their valence.
