What sets Fire Signs apart
The fire signs are hot and dry in the old physics, masculine in gender and choleric in the humoral scheme, the temperament of yellow bile. Their rulers are Mars, the Sun and Jupiter, and in Dorotheus the fire triplicity is governed by the Sun by day, Jupiter by night, with Saturn as a participating ruler. The only exaltation in the three is the Sun at 19 degrees of Aries.
