From ABC Witchcraft by Doreen Valiente 1973
One of the most frequently recurring and most beautiful motifs of medieval art, is that of the Green Man. This figure represents a human face surrounded by foliage, which it seems to be peering through.
Often the leafy branches are shown coming from the figure’s mouth, as if he were in a sense breathing them forth. Some of the oldest representations of the Green Man show him as horned.
He represents the spirit of the trees, and the green growing things of earth; the god of the woodlands. Hence he is distinctly a pagan divinity. Yet he frequently appears among the carved decoration of our oldest churches and cathedrals, especially upon such things as roof bosses and the little seats called misericords.
As an old name for inns, too, ‘The Green Man’ makes his appearance; though here he is usually explained as representing either an old-time apothecary who gathered green herbs, or else as a forester dressed in Lincoln green.
In folk plays and customes, we find the Green Man in the guise of ‘Green Jack’ or ‘Green George’. This part was enacted by a man who appeared among the May Day revellers, covered in a sort of framework of leafy garlands, so that his face peered through the leaves, like the figure in the old church carvings. At Castleton in Derbyshire, where the ceremony is ketp up to this day, he rides on horseback and is called the Garland King.
The Green Man as a woodland god, is a relic of the old pagan rites and beliefs; and his popularity as a motif of church decoration proves that for a long time in Britain, pagan and Christian concepts existed side by side. When used in decoration, the Green Man is sometimes referred to as the foliate mask; and the foliage which surrounds him is most frequently oak, the old sacred tree of Britain. So he may be the spirit that Reginald Scot in his Discoverie of Witchcraft (1584) tells us about, “the man in the oke”, who was among the fearsome company of unearthly beings that his mother’s maid used to terrify him with, when he was a boy.
I have been told, by a present-day witch in Britain who claimed to have traditional knowledge, that an old name for people who were secretly devoted to pagan lore was ‘Green Jack’s Children’. So far, I have been unable to obtain any confirmation of this; but there is no doubt that the colour green is still regarded as somewhat uncanny, even in the present day. Some people think it unlucky, and this seems to arise from the idea that it is the fairies’ colour, and they resent outsiders wearing it. It is a witches’ colour, as is its complement, scarlet: both, in a sense, being colours of life, the green of vegetable and the scarlet of animal life.
