The third decan of Sagittarius

The closing ten degrees of Sagittarius, where belief becomes something to be shown, and the older tradition puts an unexpected Saturn underneath it.

The technical picture

Degrees: 20 to 30 degrees of Sagittarius
Sun here roughly: December 11 to December 21. The boundary shifts by about a day with the leap cycle, so a birthday within a day of either end needs a calculated chart.
Sign ruler: Jupiter, over all three decans
Traditional face ruler: Saturn, from the Chaldean order
Modern triplicity ruler: Sun, by way of Leo
Do they agree: No. The two traditions disagree here, as they do on twenty-seven of the thirty-six decans.

The core of this decan

Belief wants an audience by the end of Sagittarius. Leo colors these degrees, and the effect is that the philosophy acquires a presenter. The view gets taught, performed, and to some extent embodied. Planets here are warm, confident and quite visible. There is usually a doctrine of some kind, and usually somebody being brought along.

How it differs from the rest of the sign

The opening decan of Sagittarius searches and the middle one fights. This one demonstrates. That makes it the most charismatic third of the sign and the most conscious of how the belief is landing, which the other two are not. It is also the last ten degrees of a fire sign, and it carries the summing-up quality that end-of-sign degrees traditionally have.

The two rulers

The disagreement here is the most useful in Sagittarius. Modern practice gives these degrees to the Sun, through Leo, which accounts for the presence and the warmth. The face system gives them to Saturn. Saturn at the end of Sagittarius is a real corrective, and it is the half most readings leave out: it says the philosophy has been tested, or needs to be, and that a belief which has survived doubt is what this decan is actually for.

Where the friction is

A belief with an audience is harder to revise. A planet in these degrees can find that the position has become part of the presentation, and revising it now costs standing as well as certainty. The combination produces the specific failure of this decan, which is teaching something for a few years after ceasing to be sure of it. Pride and conviction are difficult to separate here.

Working with it

Take the Saturn seriously and let the belief be tested in private, where changing it costs nothing. It helps to say plainly when you have changed your mind, since this decan can carry an old position on momentum alone. And check whether you are teaching something because it is true or because you have become the person who says it.

Questions to sit with

What are you still saying that you have stopped being sure of?
When did you last change your mind out loud?
Is the belief yours, or has it become part of how people know you?
