Sometime around 280 BCE, Berossus, a priest of Bel from Babylon, moved to the Greek island of Kos in order to teach astrology and Babylonian culture to the Greeks. With this, what Campion calls, 'the innovative energy' in astrology moved west to the Hellenistic world of Greece and Egypt. [Campion (2008) p. 84.]

The name "Sunday", the day of the Sun, is derived from Hellenistic astrology, where the seven planets, known in English as Saturn, Jupiter, Mars, the Sun, Venus, Mercury and the Moon, each had an hour of the day assigned to them, and the planet which was regent during the first hour of any day of the week gave its name to that day. During the 1st and 2nd centuries, the week of seven days was introduced into Rome from Egypt, and the Roman names of the planets were given to each successive day.
