Question

Why is the seashell the symbol for the pilgramage of Santiago de Compostela?

Answer 1

It is said that the relics of Saint James ("James" in Spanish is "Santiago") are housed in the cathedral at Santiago de Compostela. According to Wikipedia "The association of Saint James with the scallop can most likely be traced to the legend that the apostle once rescued a knight covered in scallops. An alternate version of the legend holds that while St. James's remains were being transported to Spain from Jerusalem, the horse of a knight fell into the water, and emerged covered in the shells." By the way, why did you post this under "Chile?" - Santiago de Compostela is in Spain!
