Macbain's "Celtic Mythology" is an interesting fusion of basic folklore, elaborate religious mythology, linguistics, and cultural development. With a focus on all things Celtic, it it particularly valuable for its analysis of language and comparison of ancient language to modern terminology.To the student of the occult this particular work is invaluable for its significant treatments on the deities of the Celts, and for its inclusion of then-modern lore often based on the same. Some of the material here is taken from the Gaelic language, among others.
