The number ten is the natural number of a series. ‘It is by nature that the Hellenes count up to ten and then start over again.’ It is of course the number of the fingers of the two hands. This repetition of five observed throughout nature was one of the things that led the Pythagoreans to assert that ‘all things are number’. In the Apocalypse, ten is the ‘natural’ or complete number of a series. The Pythagoreans, experimenting with pebbles, found that ten pebbles could be laid out in a triangle of 4 + 3 + 2 + 1: and this sent their minds off in imagination. — But the ten heads or crowned horns of John’s two evil beasts probably represent merely a complete series of emperors or kings, horn being a stock symbol for empires or their rulers. The old symbol of horns, of course, is the symbol of power, originally the divine power that came to man from the vivid cosmos, from the starry green dragon of life, but especially from the vivid dragon within the body, that lies coiled at the base of the spine, and flings himself sometimes along the spinal way till he flushes the brow with magnificence, the gold horns of power that bud on Moses’ forehead, or the gold serpent, Uraeus, which came down between the brows of the royal Pharaohs of Egypt, and is the dragon of the individual. But for the commonalty, the horn of power was the ithyphallos, the phallos, the cornucopia.
