Chapel foundation deed by which D. Maria de Sá, wife of Manuel da Costa, established a chapel in the monastery of Santa Cruz of Coimbra, entailing to it the third part of her assets, which included rents (foros) of wheat taken from properties on the outskirts of Coimbra. She designated Sebastião de Sá de Miranda, her relative, to administrate it, obligating him and his successors to support the celebration of an annual mass for the institutor's soul in that monastery. The entail would always be administrated by one of the institutor's relatives, on the condition that they belonged to the lineage of her grandfather, Jorge de Sá.
However, at the end of the institution D. Maria de Sá revoked this last clause, determining that the chapel's administrators were free to choose whoever they desired to succeed them.
