All things that flow and grow were regarded in early religions as a symbol
of life: fire represented the vital craving for nourishment, water was chosen for its
fertilizing powers, plants because of their verdure in spring-time. Now, all—or
very nearly all—symbols of life are also symbolic of death. Media vita in morte
sumus, observed the mediaeval monk, to which modern science has replied La vie
c’est la mort (Claude Bernard). Thus, fire is the destroyer, while water in its
various forms signifies dissolution, as suggested in the Psalms. In legend and
folklore, the Origin of life—or the source of the renewal of the life forces—takes
the form of caves and caverns where wondrous torrents and springs well up (38).
