Aldhelm of Malmesbury was one of the most prolific and influential scholars of early Anglo-Saxon England. His contemporary fame rested partly on the fact that he had been a pilgrim to Rome. This article presents new evidence for Aldhelm's literary debt to the epigraphy of early Christian Rome. Two ninth-century manuscripts from Reims contain an anthology of six epigrams which derive largely from verse inscriptions in Old St Peter's. Aldhelm quoted two of these, de Petro and de Andrea, almost verbatim in his Carmina Ecclesiastica. It is likely that Aldhelm knew these verses from first-hand observation rather than via the pages of a manuscript sylloge.
