The Golden Bough. The Roots of Religion and Folklore. By James G Frazer.
Originally published in 1890 (this edition 1981) this publication provides an intriguing insight into the world of myth, folklore and primitive customs. The Golden Bough was originally published in two volumes in 1890, but Frazer became so enamored of his topic that over the next few decades he expanded the work sixfold, then in 1922 cut it all down to this single thick edition.
