...but Celticism is mostly pretty fantasy.
One man pens a necessary attack on neo-Celticism debunking all sorts of silliness.
Yesterday I had the amusement of skimming through a bad book on the Celts, _Celtic Mysteries: The Ancient Religion_ written by devotee of Robert Graves and The Golden Bough. Lots of nonsense about Virgin-Wife-Crone manifestations of the Mother Goddess, incredibly strained trans-cultural comparisons of religion, a dash of neo-pagan dilletantism, and outright falsehoods about the content of The Cattle Raid of Cooley.
They'd be better off making a novena to St. Patrick or indulging, if that is the right word, in good old Irish asceticism.
