Toulouse Mass

It was not composed by a single individual, but is presumed to have been compiled and performed as a unit.

It is not completely clear whether the Mass portions included in the manuscript were intended as a complete polyphonic setting of the Mass, or merely represent isolated movements.

They were inscribed in empty spaces in a manuscript that otherwise contains plainchants and texts.

The manuscript is also missing a polyphonic Gloria in excelsis Deo and Credo.

However, it does include a note identifying a motet on Ite, missa est following the Sanctus and Agnus Dei (which appear adjacently in the manuscript).
