Belly/Stomach
The seat of life in Oriental thought. Fat-bellied Eastern images are symbols of prosperity rather than gluttony. The biblical story of Jonah's three days and nights in the belly of a whale was used by Jesus as an analogy for his own death and resurrection. Alchemists used the belly as an analogue of the laboratory. From: Dictionary of Symbols (Tresidder)
