'''Pope Leo IV''' (died 17 July 855) was the [[bishop of Rome]] and ruler of the [[Papal States]] from 10 April 847 to his death in 855. He is remembered for repairing Roman churches that had been damaged during the [[Arab raid against Rome]], and for building the [[Leonine Wall]] around [[Vatican Hill]] to protect the city. Pope Leo organized a league of Italian cities who fought and won the sea [[Battle of Ostia]] against the [[Saracen]]s.

==Early career==
A [[Roman people|Roman]] by birth, Leo received his early education at Rome in the monastery of St. Martin, near St. Peter's. He attracted the notice of [[Pope Gregory IV]], who made him a subdeacon; and was created cardinal-priest of [[Santi Quattro Coronati]] by [[Pope Sergius II]].<ref name=catholic/>

==Pontificate==
In April 847, Leo was unanimously chosen to succeed [[Pope Sergius II|Sergius II]]. As the attack of the Saracens on Rome in 846 caused the people to fear for the safety of the city, he was consecrated on 10 April, 847 without waiting for the consent of the emperor.<ref name=catholic/>

===Saracen defenses=== 
He immediately began to repair the damage done to various churches of the city during the [[Arab raid against Rome]]. He restored and embellished the damaged [[Basilica of Saint Paul Outside the Walls]] and [[St. Peter's Basilica]]. The latter's altar again received its gold covering (after being stolen), which weighed 206 [[Pound (mass)|pounds]] (93.4 [[kilograms]]) and was studded with precious gems. Following the restoration of St. Peter's, Leo appealed to the Christian kingdoms to confront the Arab raiders.<ref>Pierre Riche, ''The Carolingians:A Family who forged Europe'', transl. Michael Idomir Allen, (University of Pennsylvania Press, 1993), 175.</ref>

Leo also took precautions against further raids. 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 the Vatican hill by a wall.<ref name=catholic/> Leo ordered a new line of walls encompassing the suburb on the right bank of the [[Tiber]] to be built, including St. Peter's Basilica, which had been undefended until this time. The district enclosed by the walls is still known as the [[Leonine City]], and corresponds to the later [[rioni of Rome|rione]] of Borgo. 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.<ref>Gregorovius, Ferdinand. ''History of the City of Rome in the Middle Ages'', vol. 3, (Annie Hamilton, tr.), 1903 ch. III "The Leonine City" pp 95ff.</ref><ref name=catholic>{{catholic|title=Pope St. Leo IV|url=http://www.newadvent.org/cathen/09159a.htm|last=Mann|first=Horace|volume=9|year=1910|access-date=23 September 2017|inline=1}}</ref>

===Battle of Ostia=== 
In 849, when a Saracen fleet from [[Sardinia]] approached [[Portus]], Leo IV summoned the [[maritime republics]] – [[Naples]], [[Gaeta]] and [[Amalfi]] – to form a league. The command of the unified fleet was given to [[Caesar of Naples|Cesarius]], son of Duke [[Sergius I of Naples]]. Aided by a fierce storm, the league destroyed the Saracen fleet off [[Ostia (Rome)|Ostia]].<ref name=ce>[http://www.newadvent.org/cathen/09159a.htm Mann, Horace. "Pope St. Leo IV." The Catholic Encyclopedia] Vol. 9. New York: Robert Appleton Company, 1910. 23 September 2017</ref> 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 [[Raphael Rooms|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 [[synod]]s, 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.<ref>[https://archive.org/details/landsofstpeterpa0000part/page/75 <!-- quote=Guy III of Spoleto. --> Partner, Peter. ''The Lands of St. Peter: The Papal State in the Middle Ages and the Early Renaissance'', University of California Press, 1972, p. 62], {{ISBN|9780520021815}}</ref> The history of the papal struggle with [[Hincmar of Reims]], which began during Leo's pontificate, belongs properly to that of [[Pope Nicholas I|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.<ref>Asser, Life of Alfred the Great </ref>

==Death and burial==
Leo IV died on 17 July 855 and was succeeded by [[Pope Benedict III|Benedict III]], although a legend says he was succeeded by [[Pope Joan]] for two years.<ref> the span is given as 855–857; see also quotes from "The Register of Bishop Trefnan" in The Trial of Walter Brut of 1391 in Blamires, p. 259</ref> Nowadays, the story of Pope Joan is regarded by scholars as fictional.<ref>{{cite book |last=Boureau |first=Alain |translator=Lydia G.

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 [[Pope Leo I|Leo the Great]] were separated from his namesakes and given their own chapel.<ref>{{cite book|last=Reardon|first=Wendy|title=The deaths of the Popes|year=2004 |publisher=McFarland, Incorporated, Publishers |isbn=9780786415274 |url=https://archive.org/details/deathsofpopes00wend|url-access=registration}}</ref>

==Iconography==
Leo IV had the figure of a rooster placed on the [[Old St. Peter's Basilica]] or old [[Constantine I|Constantinian]] basilica<ref>ST PETER'S BASILICA.ORG - Providing information on St. Peter's Basilica and Square in the Vatican City - The Treasury Museum [http://saintpetersbasilica.org/Interior/Sacristy-Treasury/Items/Museum-8.htm]</ref> 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".<ref name=Forlong>{{cite web| url = https://www.google.com/search?tbm=bks&hl=en&q=Forlong+%22emblem+of+St+Peter%22| title = John G.
