According to a legend, a young man completely in love with a young virtuous girl, he requested her favours under a promise of marriage, when she was praying in the name of Christ of Santiago. Fearing the boy's extravagance, the young girl conceded, but he didn't keep his word. She decided to call on the bishop, who demanded to meet a witness of the events. The girl told him to ask God, who had to rip the nails off his hand to be able to take the oath.
