Sebastián Simón was a presbyter at the cathedral of Barcelona. He wishes to be buried in Chapel of Saint Joseph, in the tumb where Petrus Turrubia, formerly canon of the cathedral, was buried; or if not possible, burial in tomb of benefice holder of the cathedral.

He wants a sung mass, as we can appreciate in this fragment.

"volo in capitulo dicte ecclesie cum missa cantata ut est moris dice ipig mee sepulture In sequentibus vero duobus diebus hoc est missarum et capitis anni in dicta Capella sanct Ioseph suavissa voce"
