the maritime republics – Naples, Gaeta and Amalfi – to form a league. The command of the unified fleet was given to Cesarius, son of Duke Sergius I of Naples. Aided by a fierce storm, the league destroyed the Saracen fleet off Ostia. The Battle of Ostia was one of the most famous in history of the Papacy of the Middle Ages and is celebrated in a famous fresco by Raphael and his pupils in his rooms of the Vatican Palace in the Vatican City. Raphael's The Fire in the Borgo celebrates the incident in which, according to legend, Leo stopped a fire in the pilgrims' district by making the sign of the cross. Leo IV held three synods, the one in 850 distinguished by the presence of Emperor Louis II, but the other two of little importance. In 853, he travelled to Ravenna to settle a dispute with the archbishop. As the archbishop was on good terms with Emperor Lothair I, the pope had little success. The history of the papal struggle with Hincmar of Reims, which began during Leo's pontificate, belongs properly to that of Nicholas I. Before his death in 855 the Pope welcomed Aethelwulf King of Wessex and his sons, including the seven year old Alfred the Great, who at 5 had already met him in 853, as pilgrims to Rome. Death and burial Leo IV died on 17 July 855 and was succeeded by Benedict III, although a legend says he was succeeded by Pope Joan for two years. Nowadays, the story of Pope Joan is regarded by scholars as fictional. Leo IV was originally buried in his own monument in St. Peter's Basilica. Some years after his death, his remains were put into a tomb that contained the first four popes named Leo. In the 18th century, the relics of Leo the Great were separated from his namesakes and given their own chapel. Iconography Leo IV had the figure of a rooster placed on the Old St. Peter's Basilica or old Constantinian basilica which has served as a religious icon and reminder of Peter's denial of Christ since that time, with some churches still having the cockerel on the steeple today. It is reputed that Pope Gregory I had previously said that the cock (rooster) "was the most suitable emblem of Christianity", being "the emblem of St Peter". After Leo IV, Pope Nicholas I,
