Gerard Sasso

Gerard Sasso became known as Pierre-Gérard de Martigues due to a mistaken tradition of his place of birth being Martigues, in Provence. However, William of Tyre, writing in the late 12th century, cites Amalfi as Gerard's birthplace. This is not implausible, as merchants from Amalfi were involved in the reconstruction of the hospice in Jerusalem in the 1020s after its destruction in 1005 under caliph al-Hakim bi-Amr Allah. An alleged surname Tum, variously also Thom, Tune or Tenque, is due to an error by Pierre-Joseph de Haitze (1730), who mistook the word tunc, "then", as a name of Gerard. De Haitze's mistake was identified in 1885 by Ferdinand de Hellwald. Before the erroneous nature of the surname Tunc became clear, Italian historian Francesco Galeani Napione (d. 1830) Italianized Gerardus Tunc as Gerardo da Tonco, suggesting that he was a native of (or held possessions in) Tonco in Piedmont. ==Life==

Little is known about Gerard's life. His nationality and place of birth is unknown, but many historians claim that he was born in Scala, Campania around 1040, while tradition makes him a native of either Amalfi or Lower Burgundy (Provence). His name, Gerard, was unknown in southern Italy in the mid-11th century. He most likely was a Benedictine lay brother, possibly one of the frates conversi (i.e., men who joined the order not as boys or youths but after spending part of their adult years leading a secular life) who came to the Holy Land to serve at the abbey of St. Mary of the Latins. Around 1080, the abbot put him in charge of the Hospital of St. John in Jerusalem, which had been built on the site of the Monastery of Saint John the Baptist in the 1060s in addition to the older hospice rebuilt in the 1020s. Prior to the Siege of Jerusalem of 1099, much of the Christian population had been expelled from Jerusalem by the Fatimids to prevent collusion with the Western besiegers. Following the capture of the city by the Crusaders the Eastern Christians were gradually returned. Gerard remained behind with some fellow serving brothers to tend to the sick in the hospital. After the success of the First Crusade and the establishment of the Kingdom of Jerusalem, Gerard continued his work at the hospital, now under vastly more beneficent conditions. Godfrey of Bouillon, the first Latin ruler of Jerusalem, gave some property to the hospital, and his successor Baldwin I of Jerusalem granted it one-tenth of the spoils of a victory at the Battle of Ramla in 1101. Also in 1101, Roger Borsa, Duke of Apulia, gave a gift of 1000 bezants to Dagobert of Pisa, Latin Patriarch of Jerusalem, with the specification that one third of the gift was to go to the hospital. The patriarch unfortunately kept the gift for himself, contributing to his downfall. By 1113, the hospital was a wealthy and powerful organisation within the kingdom of Jerusalem, and Gerard expanded its operations far beyond the limits of the city, establishing daughter hospitals at Bari, Otranto, Taranto, Messina, Pisa, Asti and Saint-Gilles, placed strategically along the pilgrim route to Jerusalem. The hospital soon overshadowed the abbey of St. Mary of the Latins, which was still its nominal parent organisation, and it may be that because of this, it was deemed appropriate to establish the hospital as a sovereign entity in its own right. This happened in 1113, when Pope Paschal II in Pie Postulatio Voluntatis recognised the hospital as a new religious order. The brothers serving in the hospital were now known as the Hospitallers of St John, and Gerard as the Rector of the Hospital. The Order adopted a rule that adopted components from the Rule of St Benedict and the Rule of St Augustine. The order was now independent, subject only to the papacy (and no longer subject to the Patriarchate of Jerusalem), and free to elect Gerard's successor, and free to receive and own property. Gerard lived for another seven years. He died in his seventies on 3 September, between 1118 and 1121. He was succeeded by Raymond du Puy. ==Legacy and veneration==

, captioned Brother Gerard Tum, Founder of the Order of St John of Jerusalem 1099. The order continued to flourish under Raymond, who first used the title of Grand Master after Roger II of Sicily used this address in letters to Raymond. It was also Raymond who militarised the order. According to descriptions of the operations of hospital from the second half of the 12th century, the men's hospital was divided into eleven wards and could tend to more than 1,000 patients. The hospital admitted all sick, regardless of nationality or religion. The Hospitallers at this time also operated a field hospital that would accompany the crusader armies on expeditions, which was able to evacuate 750 seriously wounded men from the Battle of Montgisard on 25 November 1177 for treatment in Jerusalem. The Hospitallers referred to their patients as "our lords, the sick" in a tradition that presumably originated with Gerard. Relics attributed to Gerard continue to be preserved in Provençal churches, including the church of Martigues, one of his possible birthplaces. Other relics belonging to Gerard can be found in Martigues, France, in the chapel of the Magistral Palace of the order in Rome, in the church of San Domenico, Pisa and in Sicily. A stained glass window in the Church of St John-at-Hackney in Hackney features Gerard with the caption Gerard : 1st Grand Master. ==See also==
