This is a complex subject pieced together from Roman and Christian writings, oral traditions and archaeological artifacts, yet the author makes it comprehensible. Readers who enjoy compilations such as Joseph Jacobs's Celtic Fairy Tales (Dover, 1968) can use this encyclopedia to learn more about the interrelation of characters and the culture that created them. Students desiring illustrated narrative descriptions of Celtic culture and mythology may want to turn to Proinsias MacCana's Celtic Mythology (Peter Bedrick, 1985; o.p.) or Timothy R. Roberts's The Celts in Myth and Legend (MetroBooks, 1995).–Ann G. Brouse, Steele Memorial Library, Elmira, NY
