abstract:
Irish hagiography displays considerable interest in communication between Ireland and Rome, particularly as this featured saints, popes and relics. While people and objects travel between the two places, there is also concern to circumvent the distance involved. This article discusses an episode of miraculous communication in the Irish Life of St Colmán Élo. Here messages and messengers travel from Rome, but time and space are also telescoped through aural and material means: the sound of the bell marking the death of Pope Gregory the Great and a gift from him of Roman soil to be spread on Colmán Élo’s cemetery. The article considers how the two elements function within their hagiographical context to connect Rome and Ireland, and how these places shaped the account. The roles of bell and soil both draw on their associations in Ireland and relate to papal communication as this was experienced and imagined more widely.
