Between A and B there were other folios, now lost. The two surviving folios correspond to the liturgical items prescribed by the Ordinary of the Dominican Order, approved in 1256. Some of the chants (or its verses) are seldom found outside the Order. Among the sources indexed in the Cantus manuscript database, as of November 2022, only one codex of Italian origin now at Chicago (US-Cai 1911.142b) and an antiphoner from Dubrovnik (HR-Dsmbb XI) fully coincide in contents with this fragment; both, unsurprisingly, are Dominican.
Possible provenance: Elvas (district of Portalegre), where the preachers were established since 1267.
