The mythology of pre-Christian Ireland did not entirely survive the conversion to Christianity. Much of it was preserved and shorn of its religious meanings in medieval Irish literature. This grand collection of authentic Gaelic ballads and poems about the Fenni of Erin includes poems about Saint Patrick attributed to the ancient Irish Bard, Oisin, son of legendary Fionn MacCumhaill. This sparkling gem of Irish literature merges folklore with ancient history with the epic poem entitled "The Conversion of Oisin."
