This little work of religious history delves into the cultural as well as the linguistic, with its main focus being on correlating ritual and language between the Druids and Hebrews, positing a common prior origin, Antediluvian in nature. It goes into some detail about other contemporary spiritual and cultural groups as well, and while this kind of theory has largely been discarded in modern academia, it is more because of its religious connotations than any prevailing counter evidence.
