"Perhaps the ancients were right, and we mortals are merely playthings of a capricious fate." -- Tom Harper, ' Knights of the Cross'

Capricious comes, via French, from Italian capriccio, a shivering, a shudder, finally (influenced by Italian capra, goat) a whim, from capo, head (from Latin caput) + riccio, hedgehog (from Latin ericius). The basic idea is that of a head with hair standing on end, like the spines of a hedgehog.
