The painting is based on a famous old tale. An old blind man sends his son Tobias and his dog on an errand. Tobias meets a stranger on the way who helps him out when he gets attacked by a fish – and even helps him find a wife. And if that wasn’t enough, on his way home the stranger helps Tobias cure his father’s blindness. But how is this all possible? Well, the stranger is really the angel Raphael!
