P-BRad (Braga) Arquivo Distrital Pastas de fragmentos, 023 (olim Caixa 243, nº 15)
"23" was written in red ink at the top of fol. Ar, between the two columns. On the same page, on the left side, a modern hand wrote "Caixa 243, nº 15" in blue ink. At the bottom of the page there is a big annotation "Santa marimba de lousado", which gives us information about the provenance of the fragment. Santa Marinha de Lousado is located ca 30 km south-west of Braga. Immediately below this inscription there is another one now almost completely vanished (in yellow ink).
P. Avelino de Jesus da Costa referred to this fragment as: "Caixa 243, 41 – Número 15 – Tombo de Santa Maria do Lousado, 1546".
