Saint Guinefort Depiction of the medieval legend of Guinefort; Good dog. Guinefort; Greyhound; was guarding the residence where his master lived with her newborn son. Returning one day from hunting; the man saw that in her son's room there were signs of aggression and the overturned cradle; while the dog had bloody fangs. Believing that the dog had mauled; he immediately killed him with the sword; shortly after he heard the baby crying and found him unharmed under the cradle; along with a viper killed by the dog. Leaders then Guinefort had fought against the snake to save the child; the deeply repentant man buried his dog and he covered his grave stones. In a short time on the tomb of the martyr dog they went accumulating numerous votive brought in thanks of miracles and graces that; according to the people; He performed the holy dog; especially to protect children. Word of mouth lasted centuries; and the figure of Guinefort was assimilated to that of a human saint.
