Tetralogy: Meaning (information, definition, explanation, facts)

A tetralogy is a compound work that is made up of four (Greek tetra) distinct works.

The name comes from the Attic theater, where tetralogies were meant to be played in one sitting at the Dionysia. In more recent times, Shakespeare wrote a tetralogy consisting of Richard II, Henry IV, part 1, Henry IV, part 2, and Henry V.

In modern times, the term is also applied to novels, such as the ones by Ford Madox Ford and Henry de Montherlant.
