Proserpina rules Virgo, exalt in Gemini.

Preserving tendency approach Proserpina to Saturn, but Proserpina has
also opposite side - Virgo is mutable sign, sign of change of season.
Symbol of planet ]*[ can be interpreted like two Moons - two changness,
and between they point, which symbolizes fixation. Fixation of changes
(confluence of qualities of Moon and Saturn) we named will (in meaning
as self-discipline). It gives possibility to transform without destroying
of existing structures. But positive, fixing part in Virgo is stronger
(in comparison with Cancer): changes takes place hard, and at once
realizes as result.

Proserpina looks like his husband Pluto - inclination to hard anlysys,
insistentness, severance of superfluous, but she has more soberness than
sensual Scorpio and craving for riches Pluto. In future, when Proserpina
will be discovered, these preserving qualities will change to more living.

Proserpina is emotionally restraint, soul is in hard frames. Beauty
yields his place to expediency (Venus fall in Virgo). If Proserpina
feel something, these are physiological processes in organism. But it
is also kind of sensibility, and newer generations perhaps will show
it more emotionally.
