Abstract
Adomnán of Iona's work on the holy places of Jerusalem and surrounding regions has been used as a guide to seventh-century Palestine. In particular, its plans of monuments such as the Church of the Holy Sepulchre have been used by archaeologists for information about buildings, while their form interests historians of cartography. However, these plans must be read with the book's several purposes in mind. They attempt to harmonize biblical data visually. In addition, they project elements of Iona's monastic liturgy into an alien liturgical space. The plans are not simply illustrations to clarify the text but constitute a distinct, parallel text of their own, with elements shown that Adomnán would not have asserted in writing. They indicate that, for Adomnán, there were different orders of verification for written texts and visual materials such as plans.
