OGMA

[Celtic] In Irish-Celtic myth, Ogma is the god of eloquence and learning. He is the son of the goddess Danu and the god Dagda, and one of the foremost members of the Tuatha Dé Danann. He is the reputed inventor of the ancient Ogham alphabet which is used in the earliest Irish writings. In the final battle at Mag Tuireadh he managed to take away the sword of the king of the Fomorians, but had to pay with his life for this feat. His Celtic equivalent is Ogmios.
