Sign Virgo, twenty-one degrees
Phase Waning crescent
Condition Void of course
The word to know today
Bound
One of the five essential dignities, and the one modern astrology most often forgets. The bound system divides each sign into five unequal segments, each governed by one of the five visible planets. A planet sitting in its own bound holds a minor claim to that degree, somewhere between peregrine and dignified.

And by spring she’s forgetting her grandkids’ names again.

It’s heartbreaking.

And then I discovered Pumpkin Spice and special Italian Oranges can clear up her brain fog and bring her back to us.

Those were her favorites at Christmas.

So I started giving them to her every day.

But it wasn’t until I found one more ingredient that her memory really came back…

Every degree of the zodiac belongs to a planet, even when no planet is visiting. The Moon is at twenty-one degrees of Virgo tonight, waning crescent, and she has been void of course since 06:58 UTC this morning. The void is long, running past thirty hours into tomorrow afternoon.
But the degree itself carries a name most modern astrology has quietly dropped: the bound. A bound, sometimes called a term, is one of the five essential dignities. Where domicile gives a planet ownership of a whole sign and exaltation honors it in another, the bound system slices each sign into five unequal segments, each assigned to one of the five visible planets. Mercury, Venus, Mars, Jupiter, Saturn: each governs a stretch of degrees in every sign, and the Moon and Sun receive no bounds at all.
Ptolemy, writing in second century Alexandria, preserved multiple versions of the bound assignments in the Tetrabiblos and noted that the Egyptian bound table differed from the Chaldean one. He rejected both for a third version. Abu Ma’shar, writing in ninth century Baghdad, transmitted both systems into Arabic, and Bonatti in thirteenth century Italy inherited them, using bounds routinely when judging a planet’s strength at a specific degree. A planet with no major dignity but sitting in its own bound held a foothold, a minor claim somewhere between peregrine and dignified.
The Moon in Virgo holds none of her major dignities. Not her domicile, not her exaltation, not her detriment, not her fall. She is peregrine by the broad reckoning, void by the narrow one. Whether she picks up something smaller at this particular degree depends on which bound table you trust, and the tradition left more than one.

Ptolemy, Tetrabiblos
Second century Alexandria. The text that codified the bound system, preserving the Egyptian and Chaldean tables but rejecting both for a third version.
