The dominating visual feature of the clock is a sculpture of a grim-looking, devouring, metal insect similar to a grasshopper or locust. The sculpture is actually the clock's escapement (see below). Taylor calls this beast the Chronophage (literally "time eater", from the Greek χρόνος [chronos] time, and φαγω [phago] I eat). It moves its mouth, appearing to "eat up" the seconds as they pass, and occasionally it "blinks" in seeming satisfaction. The creature's constant motion produces an eerie grinding sound that suits its task. The hour is tolled by the sound of a chain clanking into a small wooden coffin hidden in the back of the clock.
