Pope from April 10, 847 - July 17, 855
Lived: 790 - July 17, 855
Give me the scoop on Leo IV.
Leo, a Roman by birth, was a very devout and holy man. Prior to being pope, he was educated at the monastery of St. Martin in Rome, served as a subdeacon under Pope Gregory IV, then as cardinal and pastor of the Church of the Quatuor Coronati (“Four Crowned Martyrs”).
Given the ruinous state of the city at the time, it appeared that the Roman nobility put aside their ambitions and let Leo be chosen as the 102nd Successor of St. Peter. Leo ensured the repair of churches damaged in the Saracen raids of 846, though St. Peter’s Basilica reportedly was never the same. In his later years, Leo held a meeting of bishops in Rome to address some disciplinary issues and to condemn an unruly bishop, Anastasius. Spoken of by both his biographer and Photius, Patriarch of Constantinople, as a worker of many miracles, St. Leo IV died July 17, 855 and was buried in St. Peter’s.
What was he known for?
That big, thick wall you can still see surrounding the Vatican Hill in Rome is thanks to none other than our venerable Pope St. Leo IV. Working quickly after being elected to protect the Eternal City from further attacks by the Saracen army, Leo set about re-fortifying the area over the course of the next four years. He had 15 towers completely rebuilt, restored the walls of the city, and built new walls on the right bank of the Tiber River to prevent a repeat of the attack that occurred under Sergius II’s watch. The newly-fortified portion was affectionately titled “The Leonine City” after the pope, and bears the same name to this day.
Leo IV is also known for organizing a fleet to combat and defeat the Saracen Army at sea in the 849 Battle of Ostia. Interestingly enough, records indicate that the Italian ships were aided in their victory by an aptly-timed wind storm. Perhaps
Someone was just practicing for another naval battle 700 years later.
Fun fact: Leo IV, whose name literally means “lion” in Latin, was the fourth-straight "Pope Leo" to be recognized as a saint after death. It’s the only papal name whose first four occupants carry the halo. Popes St. Leo I, II, III, and IV, pray for us!
What else was going on in the world at the time?
In 850, the world changed forever. According to legend, an Ethiopian goat-herder named Kaldi began to notice that his goats became surprisingly energetic after chewing berries from certain plants. When Kaldi took the berries to a monk, the monk promptly threw them into the fire, but was drawn back by the attractive smell they produced. When other monks began to gather, they soon pulled the roasted berries out of the fire, ground them, and stewed them in hot water. Thus, coffee was born. {Cries tears of joy}
