The Second Decan of Leo

This is the second ten-degree segment of Leo, the fixed fire sign, spanning 10 to 20 degrees. Its ruler in the Chaldean order of faces is Jupiter, reached by continuing the planetary sequence around the wheel of thirty-six decans. Historically the decan is the most ancient layer of the tradition: the thirty-six were Egyptian star groups, a calendar and a star-clock older than the zodiac, folded into the twelve signs three to a sign only after Babylonian astrology reached Egypt.

The Golden Dawn, from 1888, mapped the numbered minor cards onto the decans; this segment carries the Six of Wands, to which they gave the title Victory, its Jupiter-in-Leo attribution taken from the face ruler, expansive Jupiter in the regal fire sign matching the card of triumph and acclaim. That tarot layer is a modern Western construction over the ancient decan scheme, valuable for divination but not part of the inherited astronomy.
