-in Western traditional, Saturn is associated with the element earth
(thus Saturn as dispositor of earthy Capricorn)
-in the Vedic tradition, however,
Saturn is associated with the element air
(thus Saturn as dispositor of airy Aquarius)
Could Saturn be a double-element planet (earth + air)?
There is some tradition about Mercury being a double
(earth + water; air + earth)...
-then there is the theory
of the original attribution of sign "rulerships"
based on planet's relationship to the Sun:
ie,
: for the outward spread of planets going from the Sun:
Sun = Leo,
next planet Mercury = next sign Virgo,
then Venus = next sign Libra,
then Mars = Scorpio,
then Jupiter = Sagittarius,
then (final on the outward spread) Saturn = Capricon
+Then starting from the outer limit coming back toward the Sun:
: outermost (traditional planet) Saturn = Aquarius,
then next planet
(coming back inward-sunward-from Saturn) is Jupiter = Pisces,
then next planet coming sunward is Mars = Aries,
then next planet coming sunward is Venus = Taurus,
next planet coming sunward is Mercury = Gemini,
and finally a jot toward the earth, with Moon = Cancer
(Sun to Moon via the circuit of the solar system,
Leo outward through signs,
then back inward through signs, Leo to Cancer)
Could be why
(or another reason why)
Saturn allocated to Capricorn and to Aquarius,
in the olden times...
