Fionn cooked the salmon, turning it over and over, but when he touched the fish with his thumb to see if it was cooked, he burnt his finger on a drop of hot cooking fish fat. Fionn sucked on his burned finger to ease the pain. Little did Fionn know that all the salmon's wisdom had been concentrated into that one drop of fat. When he brought the cooked meal to Finn Eces, his master saw that the boy's eyes shone with a previously unseen wisdom. Finn Eces asked Fionn if he had eaten any of the salmon. Answering no, the boy explained what had happened. Finn Eces realized that Fionn had received the wisdom of the salmon, so gave him the rest of the fish to eat. Fionn ate the salmon and in so doing gained all the knowledge of the world. For the rest of his life, Fionn could draw upon this knowledge merely by biting his thumb. The deep knowledge and wisdom gained from the Salmon of Knowledge allowed Fionn to become the leader of the
