To a modern reader the connexion at first sight may not be obvious between the activity of the hangman and the productivity of the earth. - James George Frazer

If in the present work I have dwelt at some length on the worship of trees, it is not, I trust, because I exaggerate its importance in the history of religion, still less because I would deduce from it a whole system of mythology; it is simply because I could not ignore the subject in attempting to explain the significance of a priest who bore the title of King Of the Wood, and one of whose titles to office was the plucking of a bough — the Golden Bough — from a tree in the sacred grove.

With the advance of knowledge, therefore, prayer and sacrifice assume the leading place in religious ritual; and magic; which once ranked with them as a legitimate equal, is gradually relegated to the background and sinks to the level of a black art.

It is not a new opinion that the Golden Bough was the mistletoe. True, Virgil does not identify but only compares it with the mistletoe. But this may be only a poetical device to cast a mystic glamour over the humble plant.
