P-G (Guimarães) Arquivo Municipal Alfredo Pimenta C 627
A modern hand added the inscription "1578-1579 Livro da Fazenda" on the recto, left margin of the page. Another hand added an inscription on the verso (picture 2): it is in Portuguese and it could give further information about the provenance of the fragment. One more modern hand penned "A-3-1-50" on the verso side.
This is possibly one of the few fragments in Guimarães mentioned by Solange Corbin (see below) although she describes the contents as excerpts from a Marian Mass in Advent.
