The unnumbered measure the same as Barc E, but the type of the writing indicates that this folio belonged to a different codex. In the margin there are annotations from 1502 in Catalonian, which do not have any connection to the contents of the fragment. These annotations suggest that the manuscript belonged to an ecclesiastical centre of the kingdom or Aragon, such as the Royal Chapel.
