Pope Saint Leo IV was pope from April 10, 847 to July 17, 855. At a Roman synod in April 850, he crowned as co-emperor the Frankish emperor Lothar I’s son Louis II. In church affairs, Leo took a firm hand against abuses by important ecclesiastics. He censured the powerful archbishop Hincmar of Reims for excommunicating an imperial vassal without papal approval, and he excommunicated Cardinal Anastasius of San Marcello (later the antipope Anastasius Bibliothecarius), in 853, to enforce ecclesiastical obedience to Rome.

A Roman by birth, Leo had been a Benedictine monk and served in the papal curia under Pope Gregory IV. He was later appointed a cardinal by Pope Sergius II. Upon Sergius' death, Leo was unanimously chosen to succeed him on April 10, 847.

His pontificate was chiefly distinguished by his efforts to repair the damage done by the Saracens, who had attacked Rome during the reign of his predecessor. Leo supervised the fortification the city to protect it against future attacks from the Muslim enemy and several important churches of the city, especially those of St Peter and St Paul, were rebuilt under his direction.

When the Muslims fleet again threatened, he summoned the leaders of the mariner cities of Italy—Naples, Gaeta and Amalfi—to form a league. The subsequent Battle of Ostia was one of the most famous in the his of the papacy during the Middle Ages. It was celebrated in a famous fresco by Raphael and his pupils in his rooms of the Vatican Palace. Another episode of Leo's life celebrated by the Urbinate in his series of frescoes painter is the Incendio di Borgo: it depicts the great burning of the Anglo-Saxon district of Rome (the "Borgo") which, according to the legend, was stopped by Leo simply making the sign of the cross.

Leo held three synods, one of them in 850, distinguished by the presence of the holy Roman emperor Louis II. He died on July 17, 855 and was buried in St. Peter's. Benedict III was Leo's immediate successor. A medieval tradition claimed that a woman, Pope Joan, succeeded him, disguising herself as a man; Joan is generally believed to be fictitious.

Biography

Radoald

was unanimously elected to succeed Sergius II, and as the alarming attack of the Saracens on Rome in 846 caused the people to fear for the safety of the city, he was consecrated (10 April, 847) without the consent of the emperor. Leo received his early education at Rome in the monastery of St. Martin, near St. Peter's. His pious behaviour attracted the notice of Gregory IV, who made him a subdeacon; and he was created Cardinal-Priest of the church of the Quatuor Coronati by Sergius II. As soon as Leo, much against his will, became pope, he began to take precautions against a repetition of the Saracen raid of 846. He put the walls of the city into a thorough state of repair, entirely rebuilding fifteen of the great towers. He was the first to enclose theVatican hill by a wall. To do this, he received money from the emperor, and help from all the cities and agricultural colonies ( domus cultae) of the Duchy of Rome. The work took him four years to accomplish, and the newly fortified portion was called the Leonine City, after him. In 852 the fortifications were completed, and were blessed by the pope with great solemnity.

Whilst the work of refortifying the city was in progress, a great fleet of the Saracens sailed for Rome, seemingly from Sardinia, but it was completely destroyed off Ostia by the allied fleets of Rome, Naples, Amalfi, and Gaeta, and by a tempest (849). When the rebuilding of the walls of Rome was accomplished, Leo rebuilt Portus, and handed it over to a number of Corsican exiles, whom the ravages of the Saracens had driven from their homes. Other cities too in the Roman duchy were fortified, either by the pope himself or in consequence of his exhortations. Leo also endeavoured to make good the damage which the Saracen raid of 846 had done to the different churches. St. Peter's had suffered very severely, and though as a whole it never again reached its former magnificence, Leo managed to make it in parts at least more beautiful than it had been before. St. Martin's, where he had been educated, the Quatuor Coronati, of which he had been the priest, the Lateran Palace, the Anglo-Saxon Borgo, Subiaco, and many other places both in Rome and out of it were renovated by the energetic Leo. It was by this pope that the church of S. Maria Nova was built, to replace S. Maria Antiqua, which the decaying Palace of the Caesars threatened to engulf, and of which the ruins have recently been brought to light. In 850Leo associated with Lothair in the empire his son Louis, by imposing on him the imperial crown. Three years later "he hallowed the child Alfred to king [says an old English historian] by anointing; and receiving him for his own child by adoption, gave him confirmation, and sent him back [to England] with the blessing of St. Peter the Apostle."

The same year (853) he held an important synod in Rome, in which various decrees were passed for the furtherance of ecclesiastical discipline and learning, and for the condemnation of the refractory Anastasius, Cardinal of St. Marcellus, and sometime librarian of the Roman Church. Equally rebellious conduct on the part of John, Archbishop of Ravenna, forced Leo to undertake a journey to that city to inspire John and his accomplices with respect for the law. It was while engaged in endeavouring to inspire another archbishop, Hincmar of Reims, with this same reverence, that Leo died. Another man who, till his death (851), defied the authority of the pope was Nomenoe, Duke of Brittany. Anxious to be independent of the imperial authority Nomenoe, in defiance both of Leo and Charles the Bald, not only deposed a number of bishops, but made new ones, and subjected them to a metropolitan see (Dol) of his own creation. It was not till the thirteenth century that the Archbishop of Tours recovered his jurisdiction over the Breton bishops. For consecrating a bishop outside his own diocese, St. Methodius, Patriarch of Constantinople, had suspended Gregory Asbestas, Bishop of Syracuse. St. Ignatius, who succeeded St. Methodius, in consequence forbade Gregory to be present at his consecration. This led Gregory to break all bounds. St. Ignatius accordingly caused him to be deposed, and begged the pope to confirm the deposition. This, however, Leo would not do, because, as he said, Ignatius had assembled bishops and deposed others without his knowledge, whereas he ought not to have done so "in the absence of our legates or of letters from us". Despite the fact that Leo was then in opposition to the Patriarch of Constantinople, one of his dependents, Daniel, a magister militum, accused him to the Frankish Emperor Louis of wishing to overthrow the domination of the Franks by a Greek alliance. Leo had, however, no difficulty in convincing Louis that the charge was absolutely groundless. Daniel was condemned to death and only escaped it by the intercession of the emperor. Shortly after this Leo died, and was buried in St. Peter's (17 July, 855). He is credited with being a worker of miracles both by his biographer and by the Patriarch Photius. His name is found in the Roman Martyrology.

Legacy

In order to definitively counter the Saracen menace, Leo ordered a new line of walls encompassing the suburb on the right bank of the Tiber to be built, including the till now undefended St. Peter's Basilica. The district enclosed by the walls is still known as the Civitas Leonina, namely the City of Leo. He also embellished the damaged churches of St. Paul and St. Peter's: the latter's altar received again (after the former had been stolen) his gold covering, which weighed 206 lb. and was studded with precious gems.

The command of the unified fleet was given to Cesarius, son of Duke Sergius I of Naples. In 854 Leo fortified Civitavecchia, Italy, a popular Saracen target. Thereafter, the town was named Leopoli in his honour.
