This paper examines the connections between the penitential works
attributed to Gildas and David and those of the anonymous author of the Poenitentiale Ambrosianum and Cummian. It argues that the penitential attributed to Gildas should be regarded as a genuine work by Gildas and that the Ambrosianum
be considered as ‘the book of David’, from which excerpts were made.
Attempts by Cummian to combine these two authorial traditions in
seventh-century Ireland point to the continuing strength of a British
Church, against the image presented by Bede.
