Mgr. H.K. Mann's Tombs and Portraits of the Popes of the Middle Ages is a historical and artistic study detailing the tombs and portraits of popes from the medieval period, examining their creation, artwork, architecture, and symbolism within their historical context. The book includes photographic plates and illustrations of these sepulchral monuments and portraits, offering insights into the Catholic Church's art and history during the era. The work is presented as a valuable resource for understanding medieval art and the history of the Catholic Church, with some editions being facsimile reprints of culturally important, albeit sometimes imperfect, original texts.
