The decans · Virgo
Virgo first decan
If your Sun sits between 0° and 10° of Virgo, this is your decan. You share your sign with everyone born across its thirty degrees, and you share this band with about a third of them.
Your two rulers
- Triplicity
- Mercury, reached through Virgo. This scheme walks the three signs of your element in order, so a Virgo decan is coloured by Virgo without becoming it.
- Chaldean
- Sun, from the unbroken run of seven visible planets that starts at Mars in the first decan of Aries and never resets.
The two disagree here: Mercury by triplicity, Sun by Chaldean order. Neither is a mistake, and averaging them would produce a ruler no lineage uses.
You have two rulers, not one, because two schemes exist and they disagree. Both are shown here and neither is blended into the other. The triplicity scheme walks the three signs of your decan's element in order, so the Aries decans are ruled through Aries, Leo and Sagittarius. The Chaldean scheme runs one unbroken cycle of the seven visible planets, starting at Mars in the first decan of Aries and never resetting when a sign ends. They agree sometimes and part company often. If someone tells you there is one correct ruler for your decan, they are picking a lineage without telling you they picked.
The other two Virgo decans
Sun also rules 4 other decans in the Chaldean run, which is what an unbroken cycle of seven across thirty-six bands produces.
