The First Decan of Capricorn

This is the first ten-degree segment of Capricorn, the cardinal earth sign, spanning 0 to 10 degrees. Its ruler in the Chaldean order of faces is Jupiter, reached by continuing the planetary sequence around the thirty-six decans. The decans are the oldest stratum of astrology, beginning as thirty-six Egyptian star groups whose successive risings served as a calendar and a night-clock, absorbed into the Greek zodiac as ten-degree subdivisions of the signs only later.

The Golden Dawn, from 1888, mapped the numbered minor cards onto the decans in order; this segment carries the Two of Coins, to which they gave the title Change, its Jupiter-in-Capricorn attribution taken from the face ruler, the twos of the earthy suit and the cardinal earth sign matching the card's image of balancing flux and the turning of fortunes. That tarot layer is a modern Western overlay on the ancient decan scheme, not a feature of the Egyptian or Hellenistic material.
