“Mythically, this is the day of the year when the god of light is defeated by his twin and alter-ego, the god of darkness. It is the time of the year when night conquers day. And as I have recently shown in my seasonal reconstruction of the Welsh myth of Blodeuwedd, the Autumnal Equinox is the only day of the whole year when Llew (light) is vulnerable and it is possible to defeat him. Llew now stands on the balance (Libra/autumnal equinox), with one foot on the cauldron (Cancer/summer solstice) and his other foot on the goat (Capricorn/winter solstice). Thus he is betrayed by Blodeuwedd, the Virgin (Virgo) and transformed into an Eagle (Scorpio). Two things are now likely to occur mythically, in rapid succession. Having defeated Llew, Goronwy (darkness) now takes over Llew’s functions, both as lover to Blodeuwedd, the Goddess, and as King of our own world. Although Goronwy, the Horned King, now sits on Llew’s throne and begins his rule immediately, his formal coronation will not be for another six weeks, occurring at Samhain (Halloween) or the beginning of Winter, when he becomes the Winter Lord, the Dark King, Lord of Misrule. Goronwy’s other function has more immediate results, however. He mates with the virgin goddess, and Blodeuwedd conceives, and will give birth — nine months later (at the Summer Solstice) — to Goronwy’s son, who is really another incarnation of himself, the Dark Child. Llew’s sacrificial death at Harvest Home also identifies him with John Barleycorn, spirit of the fields. Thus, Llew represents not only the sun’s power, but also the sun’s life trapped and crystallized in the corn. Often this corn spirit was believed to reside most especially in the last sheaf or shock harvested, which was dressed in fine clothes, or woven into a wicker-like man-shaped form. This effigy was then cut and carried from the field, and usually burned, amidst much rejoicing. So one may see Blodeuwedd and Goronwy in a new guise, not as conspirators who murder their king, but as kindly farmers who harvest the crop which they had planted and so lovingly cared for. And yet, anyone who knows the old ballad of John Barleycorn knows that we have not heard the last of him.”
