Fintan is an Irish given name. In Irish mythology, Fintan mac Bóchra is said to be the sole survivor of the Great Flood on the island of Ireland, subsequently becoming a personification of old age and knowledge. As a shapeshifter, he appears to be identical to the Salmon of Wisdom and the name may thus have deeper roots in Celtic mythology. The mythical figure is probably the source for the use of the name in medieval and modern times.
