Night is related to the passive principle, the feminine and the unconscious. Hesiod gave it the name of ‘mother of the gods’, for the Greeks believed
that night and darkness preceded the creation of all things (8). Hence, night—like
water—is expressive of fertility, potentiality and germination (17); for it is an
anticipatory state in that, though not yet day, it is the promise of daylight. Within
the tradition of symbology it has the same significance as death and the colour
black.
