“A term used to distinguish anything out of its proper time. Shakespeare’s references to cannons in King John, a play which takes place before cannons came into use, to clocks in Julius Caesar, and to billiards in Antony and Cleopatra, are examples of anachronisms. In literature, anachronisms are sometimes used deliberately as comic devices to emphasized universal timelessness.”
