- 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 13° Leo is not simply "in Leo" — it sits in a particular decan, inside a particular bound, at a middle point of the sign. The middle degrees are the sign at full strength: settled into itself, neither arriving nor leaving.
The decan: Jupiter's ten degrees
Degrees 10 to 19 of Leo form the 2nd decan. In the Chaldean order this decan is ruled by Jupiter, which adds expansion, meaning and the benefit of the doubt to everything Leo already does.
By the triplicity system the same ten degrees belong to Sagittarius, the other fire sign whose flavour bleeds in here. Read together: Leo's i will, delivered with Jupiter's expansion.
The bound: Saturn's degrees
The Egyptian bounds divide each sign into five unequal stretches, each governed by one of the classical planets. 13° falls in Saturn'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 Taurus degree
Modern degree theory runs the twelve signs through the thirty degrees, so every degree carries a second sign's flavour. 13° is a Taurus degree — fixed earth: the sign of holding. In Leo, that reads as Leo's i will coloured by Taurus's i have: two different instincts sharing one degree — warmly, expressively, with the whole of itself, but with Taurus'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 13° Leo
What this degree does depends entirely on which body is sitting on it. The Sun at 13° Leo is an identity; the Moon at 13° Leo is a need; Mars there is a way of fighting. Start with the body, then add the degree:
