Will made by padre Pedro da Costa in which he ordered, among other dispositions, the foundation of an entail with a perpetual mass obligation of two masses celebrated every week, on saturdays and sundays, in his chapel of N. Sra. das Candeias, in the church of S. Lourenço of Portalegre . He named his adopted [perfilhado] son João da Costa Pereira as first administrator of the chapel and after his death, the succession should always continue, preferably, on the eldest male heir. If João died without heirs, the administration should be handled to Manuel da Costa Barbeiro, who lived in Castille and after his death to the Confraria do Santíssimo Sacramento. All administrators should give in every two years one alqueire of oil to maintain a lamp perpetually lit on the chapel. The institutor left specific instructions for the ornamentation of the chapel, ordering the administrator to place two paintings of S. João Batista and S. Miguel Arcanjo, as well as an image of Menino Jesus over the eagle over the altar of Santíssimo Sacramento.
