The Island of the Mighty

Blurb

The Island of the Mighty is a fantasy novel by Evangeline Walton, the earliest in a series of four based on the Welsh Mabinogion. It was first published in 1936 under the publisher's title of The Virgin and the Swine. Although it received warm praise from John Cowper Powys, the book sold poorly, and as a result none of the other novels in the series reached print at the time. Later rediscovered by Ballantine Books, it was reissued under the present title as the eighteenth volume of the celebrated Ballantine Adult Fantasy series in July, 1970, with an introduction by Lin Carter and a cover by Bob Pepper. It has been reprinted a number of times since, and gathered together with Walton's other Mabinogion novels by Overlook Press as the omnibus The Mabinogion Tetralogy in 2002. The novel has also been published in translation in several European languages.
The novel is a retelling of the story of the Fourth Branch of the Mabinogion, Math Fab Mathonwy, and hence is chronologically last in Walton's Mabinogion novels, though published first. The three other novels in the series are The Children of Llyr, The Song of Rhiannon, and Prince of Annwn.
