The Irish-Celtic god of the earth and treaties, and ruler over life and death. Dagda, or The Dagda, ("the good god") is one of the most prominent gods and the leader of the Tuatha Dé Danann. He is a master of magic, a fearsome warrior and a skilled artisan. Dagda is a son of the goddess Danu, and father of the goddess Brigid and the god Aengus mac Oc. The Morrigan is his wife, with whom he mates on New Years Day

The Dagda is portrayed as possessing both super- human strength and appetite. His attributes are a cauldron with an inexhaustible supply of food, a magical harp with which he summons the seasons, and an enormous club, with one end of which he could kill nine men, but with the other restore them to life. He also possessed two marvellous swine---one always roasting, the other always growing---and ever-laden fruit trees.

One of his epithets is Ollathir, which means "All-father". He is identified with the Welsh Gwydion and the Gallic Sucellos.
