- An ordinary degree, read through its decan and bound
Every sign is thirty degrees wide, and a placement's exact degree changes how the sign reads. A planet at 23° Leo is not simply "in Leo" — it sits in a particular decan, inside a particular bound, at a late point of the sign. Late degrees carry the whole sign behind them. They are the most experienced version of the sign, and the most aware that the next one is coming.
The decan: Mars's ten degrees
Degrees 20 to 29 of Leo form the 3rd decan. In the Chaldean order this decan is ruled by Mars, which adds drive, heat and the willingness to fight for it to everything Leo already does.
By the triplicity system the same ten degrees belong to Aries, the other fire sign whose flavour bleeds in here. Read together: Leo's i will, delivered with Mars's drive.
The bound: Mercury's degrees
The Egyptian bounds divide each sign into five unequal stretches, each governed by one of the classical planets. 23° falls in Mercury's bound. In traditional practice the bound ruler is a quieter but real influence — it describes the working conditions a planet meets at this exact degree, and it is one of the reasons two planets in the same sign can behave so differently.
Degree theory: the Pisces degree
Modern degree theory runs the twelve signs through the thirty degrees, so every degree carries a second sign's flavour. 23° is a Pisces degree — mutable water: the last sign, where boundaries thin. In Leo, that reads as Leo's i will coloured by Pisces's i believe: two different instincts sharing one degree — warmly, expressively, with the whole of itself, but with Pisces's instinct underneath.
Degree theory is a modern layer rather than a traditional one, and astrologers differ on how much weight to give it. It is most convincing when a chart has several planets on the same degree number.
A planet at 23° Leo
What this degree does depends entirely on which body is sitting on it. The Sun at 23° Leo is an identity; the Moon at 23° Leo is a need; Mars there is a way of fighting. Start with the body, then add the degree:
