"Celtic Mythology" is a study on ancient folk tales and legends of old Ireland, Wales and other Celtic regions, which remained a precious legacy to their illustrative history. The book deals with different aspects of folklore and mythology: myths of the creation, tales of gods and their position and behavior, the mythical creatures and animals, folk tales of the divine land and many more. Well grounded in history and sociology, the author relates these folk tales, legends and myths of Gaelic, Brythonic and Gaulish people to each other and explores the influence of Christianity on their development through the ages. "The Religion of the Ancient Celts" is an exhaustive and comprehensive study of the Celtic religion. It provides insights into Celtic religious practices, and comparisons geographically as well as with more familiar Roman and Christian pantheons. The author offers numerous interpretations and overlaps regarding the mythological roles of gods and goddesses. The Celts interacted with many cultures over the years and adopted their gods and combined with theirs. Roman and Greek gods were adopted as were Vikings' and Christianity later.
