A contemporary Jewish communication confirms the destruction of the synagogue, though it does not corroborate that any Jews were inside it when it was burned. This letter was discovered among the Cairo Geniza collection in 1975 by historian Shelomo Dov Goitein. Historians believe that it was written just two weeks after the siege, making it "the earliest account on the conquest in any language." Additional documentation from the Cairo Geniza indicates that some prominent Jews held for ransom by the Crusaders were freed when the Ascalon Karaite Jewish community paid the requested sums of money. Contrary to what is sometimes alleged, no eyewitness source refers to Crusaders killing Eastern Christians in Jerusalem, and early Eastern Christian sources (Matthew of Edessa, Anna Comnena, Michael the Syrian, etc.) make no such allegation about the Crusaders in Jerusalem. According to the Syriac Chronicle, all the Christians had already been expelled from Jerusalem before the Crusaders arrived. Presumably this would have been done by the Fatimid governor to prevent their possible collusion with the Crusaders. The Gesta Francorum claims that on Wednesday, August 9, two and a half weeks after the siege, Peter the Hermit encouraged all the "Greek and Latin priests and clerics" to make a thanksgiving procession to the Church of the Holy Sepulchre. This indicates that some Eastern Christian clergy remained in or near Jerusalem during the siege. In November 1100, when Fulcher of Chartres personally accompanied Baldwin on a visit to Jerusalem, they were greeted by both Greek and Syrian clerics and laity (Book II, 3), indicating an Eastern Christian presence in the city a year later. On 17 July, a council was held to discuss, Who shall be crowned the king of Jerusalem? On 22 July, Godfrey of Bouillon (who played the most fundamental role in the city's conquest) was made "Advocatus Sancti Sepulchri" ("advocate" or "defender of the Holy Sepulchre") on July 22, refusing to be named king in the city where Christ had died, saying that he refused to wear a crown of gold in the city where Christ wore a crown of thorns. Raymond had refused any title at all, and Godfrey convinced him to give up the Tower of David as well. Raymond then went on a pilgrimage, and in his absence Arnulf of Chocques, whom Raymond had opposed due to his own support for Peter Bartholomew, was elected the first Latin Patriarch on August 1 (the claims of the Greek Patriarch were ignored).
