From the early Middle Ages to modern times, Williams (Simon & June Li Fellow in the Humanities, Univ. of Oxford; Fiery Shapes: Celestial Portents and Astrology in Ireland and Wales 700–1700) guides readers through an examination of the history and development of Irish gods and their myths. Discussions include topics such as how stories and characteristics of the pre-Christian gods changed when Christianity was introduced (e.g., the pagan god Lugus's transformation into the literary Lug), the effects of Irish gods and mythology on history and culture (e.g., the emergence of "Celtology"/Celtic studies), the Irish gods in literature and art (e.g., the work of W.B. Yeats, George Russell, and impact of the Literary Revival), and more. Examinations of ancient and modern Irish sagas, poems, and other narratives such as "The Tragic Deaths of the Children of Lir" and Standish James O'Grady's two-volume History of Ireland appropriately frame these discussions. Includes a glossary and pronunciation guide. VERDICT Scholarly, complete, and engaging, this volume will complement existing works on the topic. Strongly recommended for students, scholars, and fans of Irish mythology and literature.—Jennifer Harris, Southern New Hampshire Univ. Lib., Manchester
