This ancient illumination is from a manuscript all the way back to the 1300s. Astronomers believed the sun, the moon, Mars, Venus, Mercury, Saturn and Jupiter revolved around earth. It was also noted that the moon’s four phases lasted 7 days each.
In the Bible, more sevens abound. The seventh day sabbath starts in Genesis and Revelation warns us of a 7 headed beast. Las Vegas slot machines pay out on triple 7s and the game of craps is all about 7 come 11.
