A bulb that thinks it's a candle

Le Grand Siècle, at the Puy du Fou. The decor replays the seventeenth century down to the smallest detail: a brass sconce with star-engraved glass, set against a blue wall covering dotted with gold diamonds, edged by a damask curtain. Nothing here is period, and yet the eye believes it. Perhaps that is the real show: a bulb that thinks it’s a candle.
