Four Temperaments: PHLEGMATIC
The four temperament theory is a proto-psychological theory which suggests that there are four fundamental personality types: Sanguine, Phlegmatic, Choleric, and Melancholic.  Hippocrates described the four temperament many years ago (c. 460 – c. 370 BC) . The artist Lotte Lambæk has made her own visual expression of the Four Temperaments.
