There are several versions of myths about seven brothers, each with a different talent. In this version the brothers' abilities are even more exaggerated than usual, and they use them to help a rather malingering Finn mac Cool save the baby of the King of the Giants, whose other sons have all been kidnapped at birth.
The story is charmingly told, humorous and sympathetic without being cutesy or affected. Finn has a headache and wants to be left alone, but when he hears of the giant king's sadness he wants to help him. Finn is motivated not by desire for fame or reward, but by paternal sympathy. With sobs the giant tells him of the stolen babies, and Finn
thought of his own son Oisin reared to manhood and he thought of his grandson Oscar and how sweet he was. He remembered that he had said that he would love Oscar tomorrow but not today; and he knew he was lucky to be able to say such a thing. Pity for the king filled his heart.
