abstract:
The Vatican MS, BAV, Reg. lat. 123 (saec. xi, Ripoll), a computistical anthology, contains numerous excerpta of ultimate Irish provenance. Some of these materials may have reached Ripoll through a route of transmission that brought them first to Brittany, and from there to the scriptoria of Fleury-sur-Loire and Ripoll itself.
