Chaldean order

Also called: chaldean

The seven classical planets arranged by how slowly they appear to move: Saturn, Jupiter, Mars, Sun, Venus, Mercury, Moon. Walking that list one planet per hour, and then taking every twenty-fourth hour, produces the order of the days of the week — which is why Saturday follows Friday rather than following Saturn’s neighbour in the list. It is older than the zodiac.
