To mathematicians the nautilus shell personifies the Golden ratio on the one, two, and three-dimensional planes. One-dimensionally, it is the linear spiral, which is based on the Golden ratio. Two-dimensionally, with area, the shell itself can be contained in a Golden proportioned rectangle; and three-dimensionally each chamber has approximately 1.618 times more volume than the chamber preceding it.
The seashell is the mystic symbol of prosperity and regeneration and, in its association with the sea, is the source of fertility. It is in the sea that life originated. The mythic birth of Venus from a shell heightens the prehistoric call of the sea where mythology plays the eternal game of life and death. It stands for the beginning and the end, it is the memory of time.
