This little booklet is a good example of the type of work considered of especial interest in the era- the study of past civilizations and the origins of mankind and of his spirituality were common literature in the early 20th century.It speaks of the Druids, the divisions of Celtic society, its development (which is slightly dated now despite partial apparent accuracy) and more. To the occultist, it represents a good, concise overview of the basic tenets of pre-christian Celtic society.
