'...Saturn predominates matters related to earth,Saturn brings out only the worst qualities of Aquarius.
Uranian influence brings out both the good and the bad.
but also to water
because the element is most abundant in cold...'
I like the word ''predomination'' because the temperament of the place
could be related to many planets
like the heat of Leo is related to both Sun and Mars, but
because Leo is moderately, not extremely dry, it is predominated by the Sun.
Similarly, the cold of Aquarius is related to both Saturn and Moon, but
because Aquarius is the coldest sign, it is predominated by Saturn
and not by the Moon.
