Witta: An Irish Pagan Tradition (Llewellyn's World Religion & Magick)

Rather than focusing purely on Celtic mythology, Witta examines the cultural aspects of Irish paganism and serves as a textbook for the practice of the old religion of Ireland. It's clearly written, well detailed and researched with a fair bibliography plus history, spells, rituals, sabbats and more. The author supplies a list of resources for hard to find herbs, ritual tools and other important implements.
