he Enneagram of Personality, or simply the Enneagram (from the Greek words ἐννέα [ennéa, meaning "nine"] and γράμμα [grámma, meaning something "written" or "drawn"[1]]), is a model of the human psyche which is principally understood and taught as a typology of nine interconnected personality types. Although the origins and history of many of the ideas and theories associated with the Enneagram of Personality are a matter of dispute, contemporary Enneagram theories are principally derived from the teachings of the Bolivian psycho-spiritual teacher Oscar Ichazo from the 1950s and the Chilean psychiatrist Claudio Naranjo from the 1970s. Naranjo's theories were also influenced by some earlier teachings about personality by George Gurdjieff and the Fourth Way tradition.
