This article examines a group of manuscripts produced in England in the late twelfth/early thirteenth century and compares their artistic penwork, particularly looking at litterae florissae and linefillers. Some of these manuscripts have already been linked by their decorated initials, and were thought to be produced in a workshop in Oxford. By looking closely at the style of flourished letters, it was possible to identify a precise standard of creating letterforms, further linking these manuscripts to one production centre in Oxford. English litterae florissae and linefiller styles have not received much academic analysis to date, but finding similarities between letter styles has the potential to provide further identification for manuscript production andworkshop standards.
