"I have always regretted that We could not find time to make a Pilgrimage to Saint Iago de Compostella. We were informed, ... that the Original of this Shrine and Temple of St. Iago was this. A certain Shepherd saw a bright Light there in the night. Afterwards it was revealed to an Archbishop that St. James was buried there. This laid the Foundation of a Church, and they have built an Altar on the Spot where the Shepherd saw the Light. In the time of the Moors, the People made a Vow, that if the Moors should be driven from this Country, they would give a certain portion of the Income of their Lands to Saint James. The Moors were defeated and expelled and it was reported and believed, that Saint James was in the Battle and fought with a drawn Sword at the head of the Spanish Troops, on Horseback. The People, believing that they owed the Victory to the Saint, very cheerfully fulfilled their Vows by paying the Tribute. ...Upon the Supposition that this is the place of the Sepulchre of Saint James, there are great numbers of Pilgrims, who visit it, every Year, from France, Spain, Italy and other parts of Europe, many of them on foot.
