The Religion of the Ancient Celts - J. A. Macculloch - Bog

1911. In this work, MacCulloch attempts to rebuild Celtic paganism and to guess at its inner spirit. He portrays the Celt as a seeker after God, linking himself by strong ties to the unseen and eager to conquer the unknown by religious rite and magic art. The earliest aspect of his religion was the cult of nature spirits and of life manifested in nature.
