The Deer is the symbol of swiftness, strength, and mobility. It was central to the stories of the Fianna. Fionn Mac Cumhaill, the last leader of the Fianna, was out hunting when his hounds came across a handsome young boy who had been raised by deer. Fionn recognised him as his own son and named him Oisín meaning little fawn. Oisín's mother Blaí Dheirg was believed to be from the otherworld and wooed Fionn Mac Cumhaill into the forest. She gave birth to Oisín in the form of a deer.
