Fibonacci numbers, decanates, and antiscia
David Cochrane
Decanates (also called decans) are a division of zodiac signs into 3 sections of 10 degrees each. Amazingly, assigning Fibonacci numbers to the modern system of decanate signs produces numbers that are symmetrical around the 0-Aries / 0-Libra axis in the same pattern as antiscia signs. All Fibonacci numbers of contra-antiscia signs add up to 9.
