In 1184, Heraclius (Latin Patriarch of Jerusalem), along with Roger des Moulins, Grand Master of the Knights Hospitaller and Arnold of Torroja, Grand Master of the Knights Templar, travelled to Europe. They carried with them the keys to the city of Jerusalem, the Holy Sepulchre and the Tower of David, along with other memorabilia.
The mission visited Italy, France and England. Here they had several meetings with Henry II at Reading and at London (consecrating the church at the new Hospitallers' priory and headquarters at Clerkenwell). The king then accompanied the mission to France, where a further meeting was held in early May 1185 with Philip II and it was agreed to send both men and money to the Holy Land. This did not satisfy Heraclius, who had hoped to take back with him either Henry himself or one of his sons. Henry had promised to go on crusade years before after the murder of Thomas Becket; Heraclius reminded him of the vow and declared him and his children to be of the devil when Henry chose to stay at home.
The priory at Clerkenwell burned down and the arch stone found its way to Exmouth to the local branch of the St John's Ambulance Brigade successors to the Hospitallers (known in full as the Sovereign Military Hospitaller Order of St. John of Jerusalem of Rhodes and of Malta, Order of St. John, Knights of Malta).
Lo and behold:
