The ”Enneagram of Personality” is another typology with 9 personality types. Just like with Belbin's typology, the enneagram is often used in business life for teambuilding. The system is said to have been derived from Sufi mystics, but
this claim is not supported. Instead its creators include such names as Oscar Ichazo, Claudio Naranjo G. I. Gurdjieff.
Since astrology has 12 types, and the enneagram only has 9 types, it is no wonder that 3 of the astrological types are missing in
the enneagram, among them the Taurus / Eris type. The explanation why the Taurus / Eris type is missing in the enneagram is obvious: Some types are more visible than other types, and in traditional astrology Taurus belongs to the "invisible" signs, which include
Taurus, Virgo, Scorpio and Pisces.
The invisibility of Taurus express itself in curious way: When you read astrology books containing descriptions of the 12 zodiacal signs, you can almost always expect Taurus to have the shortest description - as if
Taurus was "beyond description".
