In Celtic mythology, Fintan (the salmon of wisdom) was a shape-changer. He was the only Irish survivor of Noah' s flood, changing into a hawk to soar above the waters and into a salmon to live in them. He ate the gods' magic hazelnuts and received all knowledge, but was netted in a salmon- trap and cooked for the gods' banquet by Finn MacCool who in doing touched Fintan's flesh and absorbed the knowledge from Fintan turning him into a seer and healer on the spot.
