Private letter from dona Filipa de Jesus de Portugal, a nun, to dona Constança de Noronha, reverend mother.
The author tells the addressee how ill she has been, with tonsillitis and malaria, and how she must hide to be able to write without the other nuns knowing it.
Dona Filipa de Portugal was the daughter of Dom António prior do Crato, claimant of the Portuguese thrown during the succession crisis after the death of Dom Sebastião in 1578. When Felipe II of Spain was crowned king of Portugal, he allegedly persecuted the daughters of Dom António, arresting them in Castilian convents.
