In the Basilica of Saint Paul’s Outside the Walls in Rome, one can find a series of mosaic portraits of the popes from Saint Peter all the way to Pope Francis. The project began with Pope Leo the Great (440-461) but a fire destroyed the Basilica in 1823. Only 40 portraits were saved. In 1847, Pope Pius IX (1846-76) revived the project which, of course, is ongoing.
