The Irish God of the Sea.
A collection of stories about Manannan mac Lir has been translated and freely adapted by the author with the intention of being suitable for children. In these stories Manannan serves as a tester and a teacher to the mortals he encounters. Sometimes he appears as a nobleman, and sometimes as a churl; sometimes he imparts his wisdom gently, and sometimes gingerly; sometimes
he teaches philosophy, and sometimes good manners, but he always seems to have the best interests of civilization at heart.
