Although the four humours were located in the human body, the basic pattern of four was used to explain a wide variety of phenomena.

For example the blood humour was assocated with the spring seaon, the element of air, and the qualities of warm and moist.

So, the balance of the humours in a person or group of people would be influenced by such things as the time of year and their geographic location.

Thus people in different locations (warm and moist as opposed to cold and moist)would be expected to display different temperaments.
