The Boyhood of Fionn by James Stephens

He was a king, a seer and a poet. He was a lord with a manifold and great train. He was our magician, our knowledgable one, our soothsayer. All that he did was sweet with him. And, however ye deem my testimony of Fionn excessive, and, although ye hold my praising overstrained, nevertheless, and by the King that is above me, he was three times better than all I say. - Saint Patrick

Fionn1 got his first training among women. There is no wonder in that, for it is the pup's mother teaches it to fight, and women know that fighting is a necessary art although men pretend there are others that are better. These were the women druids, Bovmall and Lia Luachra.
