 Gaspar do Rego da Fonseca held the see four years (1635–39).King Philip III named Francisco Pereira Pinto, but the revolution in 1640 prevented his taking possession; moreover he never received his bulls of consecration and installation from Pope Urban VIII, and therefore he could not be consecrated or installed as bishop.The diocese was considered vacant until 1670, being ruled by administrators appointed by the Chapter of the Cathedral (Vicars capitular).
