In Greek mythology, Talos, also spelled Talus or Talon, was a giant automaton made of bronze to protect Europa in Crete from pirates and invaders. He circled the island's shores three times daily.

An automaton is a relatively self-operating machine, or control mechanism designed to automatically follow a sequence of operations, or respond to predetermined instructions. Some automata, such as bellstrikers in mechanical clocks, are designed to give the illusion to the casual observer that they are operating under their own power or will, like a mechanical robot. The term has long been commonly associated with automated puppets that resemble moving humans or animals, built to impress and/or to entertain people.
