anachronism
(from Greek ana, "back," and chronos, "time"), neglect or falsification, intentional or not, of chronological relation. It is most frequently found in works of imagination that rest on a historical basis, in which appear details borrowed from a later age; e.g., a clock in William Shakespeare's Julius Caesar, an attendant to the Pharaoh shod in tennis shoes in Cecil B. deMille's The Ten Commandments. Anachronisms originate in disregard of the different modes of life and thought that characterize different periods or in ignorance of the facts of history.
