The Celt, and his cromlechs, and his pillar-stones, these will not change much – indeed, it is doubtful if anybody at all changes at any time. In spite of hosts of deniers, and asserters, and wise-men, and professors, the majority still are adverse to sitting down to dine thirteen at a table, or being helped to salt, or walking under a ladder, of seeing a single magpie flirting his chequered tale. There are, of course, children of light who have set their faces against all this, although even a newspaperman, if you entice him into a cemetery at midnight, will believe in phantoms, for everyone is a visionary, if you scratch him deep enough. But the Celt, unlike any other, is a visionary without scratching.

W.B. Yeats
