The Number 4
The number of order in the universe is 4—the four elements of earth, air, fire, and water; the four seasons; the four points of the compass; the four phases of the Moon (new, half-moon waxing, full, half-moon waning). The Four Noble Truths epitomize Buddhism. To the Pythagoreans 4 was the source of the tetractys 1 + 2 + 3 + 4 = 10, the most perfect number. In medieval times there were thought to be four humors (phlegm, blood, choler, and black bile—hence the adjectives phlegmatic, sanguine, choleric, and melancholic), and the body was bled at various places to bring these humors into balance.
Because 4 is generally a practical, material number, few superstitions are associated with it. An exception is in China, where 4 is unlucky because she (“four”) and shi (“death”) sound similar. In the biblical Revelation to John the Four Horsemen of the Apocalypse wreak destruction upon humanity. ~ Encyclopaedia Britannica
