Definitions for "Dispositor"
Keywords:  ruler, mars, leo, planet, venus
The planet which is lord of the sign where another planet is.
The planet that rules the sign or dignity another planet occupies. For example, if Mars is in Libra, the dispositor of Mars is Venus.
The dispositor of a planet is the ruler of the sign in which the planet is placed. Example: If the Moon is in the sign of Leo then the Sun (which is the ruler of Leo) is the Moon's dispositor. However, an exception to this rule can be found if the Almuten of a planet is calculated. For example, if Saturn is at 18°AR45' the Almuten of that longitude is the Sun, not Mars, which means the Sun becomes Saturn's dispositor.
A disposer.
