St Edmund, king and martyr (an Anglo-Saxon king martyred by the Vikings in 869) was one of the most venerated English saints in Ireland from the 12th century. In Dublin, St Edmund had his own chapel in Christ Church Cathedral and a guild, while Athassel Priory in County Tipperary claimed to possess a miraculous image of the saint. In the late 14th century the coat of arms ascribed to St Edmund became the emblem of the king of England’s lordship of Ireland, and the name Edmund (or its Irish equivalent Éamon) was widespread in the country by the end of the Middle Ages. This article argues that the cult of St Edmund, the traditional patron saint of the English people, served to reassure the English of Ireland of their Englishness, and challenges the idea that St Edmund was introduced to Ireland as a heavenly patron of the Anglo-Norman conquest.
