Liber Pontificalis
Modern editions include those of Louis Duchesne ("Liber Pontificalis. Texte, introduction et commentaire", 2 vols., Paris, 1886–92) and Theodor Mommsen ("Gestorum Pontificum Romanorum pars I: Liber Pontificalis", Mon. Germ. hist., Berlin, 1898). Duchesne incorporates the "Annales Romani" (1044–1187) into his edition of the "Liber Pontificalis", which otherwise relies on the two earliest known recensions of the work (530 and 687). Mommsen's edition is incomplete, extending only until 715. Translations and further commentaries appeared throughout the 20th century.
