This is a personality test of the four Ancient Greek temperaments.

In Ancient Greek medicine, illness was believed to be caused by an imbalance in four types of body fluids: blood, yellow bile, black bile, and phlegm. The temperaments idea grew out of this with the idea that a persons personality was characterized by one humor. The temperaments are sanguine, choleric, melancholic, and phlegmatic.

The ancient four temperaments have been claimed as inspiration for a wide variety of systems. Recently the four temperaments theory has been popularized by Christian and self-help writers, this is the conception that this test follows.

This test consists of 40 adjectives, for each you must indicate how much like you it is on a five point scale.
