Tractatus de summis pontificibus
Tractatus de summis pontificibus contains revelations of Birgitta written 1348–1373 and not compiled into the eight books of Revelationes. They concern Birgitta's relationship with the popes of her time. This work was compiled by Alfonso of Jaén after writing his commentary on the election of Urban V, the Informaciones, in which he defends the pope against antipope Clement VII.
