In Jewish legend, a golem is an image or form that is given life through a magical formula, such as the power of the letters of the divine name. The word is used to denote anything that is not yet fully developed. In the Middle Ages is was believed that there were wise men who could instill life in effigies by the use of a magic spell. These golems then took the form of a robot, or automaton. They would carry out their master's command and could perform easy tasks, as well as protecting their creators.
