The relics of the Magi who had visited the infant Jesus were enshrined at the cathedral at Cologne in the twelfth century, where they became an important focus of pilgrimage. The cult was widespread and diverse in form, and was especially focused on the season of Epiphany; devotional practices included formal liturgical rites, representative drama, and the invocation of the Magi in medical remedies. This chapter considers the relationship between such categories as devotional and liturgical in relation to examples of the cult in Insular sources. In particular, the presence of a votive Mass for Travellers of the Three Kings of Cologne, as found in a fifteenth-century manuscript belonging to priest Henry Wells, presents an opportunity to consider individuals for whom the cult held particular significance.
