Retro Tech: 16th Century Clockwork Monk

This is pretty hoopy - a self-acting automaton of a monk from circa 1560.

In the Smithsonian Institution is a sixteenth-century automaton of a monk, made of wood and iron, 15 inches in height. Driven by a key-wound spring, the monk walks in a square, striking his chest with his right arm, raising and lowering a small wooden cross and rosary in his left hand, turning and nodding his head, rolling his eyes, and mouthing silent obsequies. From time to time, he brings the cross to his lips and kisses it. After over 400 years, he remains in good working order.
