With the original use of the Enneagram symbol, the circle represented the sequential clockwise movement of a process as it proceeded stepwise from point 1 to point 9. For the Enneagram personality types the circle is utilized in a different way.

**The nine personality types of the Enneagram are represented by the numbers located around the circle of the symbol. The relationship between types can be inferred by where those numbers are located on the circle and where they are relative to one another. The circle is a way to explore how certain pairs or sets of types are similar and/or different as well as any special influence they have on each other.**

### The adjacent types or wings

It is sometimes said that a type is the product of the two types on either side as seen on the circle of the Enneagram symbol. Type 9 could then be thought of as a product of types 8 and 1.

Looking at this another way, the types on either side have a unique influence upon the type in the middle. This forms the basis of the wing theory in the Enneagram type system.

The wings are discussed elsewhere on this website.

### The opposite types

The concept of antipodes is briefly discussed by Claudio Naranjo in his book Character and Neurosis. He draws similarities between the types opposite one another on the circle (you have to disregard types 3, 6, and 9 to find these antipodes).

The three antipode pairs are: 1-5, 4-8, and 7-2.

Refer to Character and Neurosis for more.

### Type influences via the lines and arrows

The lines and arrows point to influences between the types around the circle such as: connecting points, stress/security points, and directions of integration/disintegration.

The lines and arrows are discussed elsewhere on this website.

### Three groups of three

Triads group types around the circle to describe similarities between the three types in a group and differences between the groups themselves using concepts such as: centers of intelligence and stances.

Triads are discussed elsewhere on this website.
