How these two meet

Gemini and Capricorn: a promise neither of you noticed making.

A promise gets made on a Tuesday and neither of you notices it being made. Gemini says a thing that is true at the moment of saying it, and Capricorn writes it down.

Nothing has been agreed. Capricorn believes something has been agreed, and is not being unreasonable about it: in Capricorn’s experience, saying a thing out loud in a serious tone is the mechanism by which things become real.

Mercury turns back 315 times a century and spends nearly a fifth of its life going over ground it has already crossed. Saturn takes 29.43 years for the twelve signs and does not revisit anything. One of these is a body for which a statement is a position taken. The other is a body for which a statement is a thought passing through.

And the ones who are not here: Gemini’s opposite is Sagittarius, who takes a passing thought and turns it into a direction without ever pretending it was a promise, and Capricorn is what comes just after Sagittarius and does not do that. Capricorn’s opposite is Cancer, who hears the tone underneath the words and answers the tone, and Gemini is what comes just before Cancer and answers the words.

What would either of you have to explain from the beginning?

For Gemini, the work is marking one sentence as provisional at the moment of saying it, out loud, in the same breath.

For Capricorn, the work is asking whether a thing was a decision, on the day, instead of filing it and finding out in March.

And a third: neither of you is being careless and neither of you is being rigid. You are running two different definitions of what a sentence is for.

Mercury changes its mind 315 times a century and Saturn has not gone back over anything in decades, and there is no shared element, modality or polarity between you to make either of those legible to the other.

How many of the things one of you is holding were ever actually handed over?

150 degrees apart

A hundred and fifty degrees apart, and like the semi-sextile it is not one of the five aspects Ptolemy kept. Signs five along share nothing: not the element, not the modality, not the polarity. The semi-sextile comes up as empty-handed, but its two signs at least touch. These two are most of the way across the wheel from each other with no common ground at any point along it, which is why the terms keep having to be invented as you go.

A sign is still a general lens: it says nothing about where your Moon or your Venus actually fell. A synastry report reads your two real birth charts against each other, with the aspects that are genuinely there.
