From the previous posting, you now know the ancient mythology of the bull representing the moon and its symbolism of the life cycle, and the lion representing the sun and its symbolism of the spiritual world.
Egyptian tombs show a change in their religious viewpoint. In earlier tombs, the furniture—sofas, tables, and such—all have feet carved in the shape of a bull’s hoof. Abruptly, the later ones all have the feet carved in the shape of a lion’s paw.
In India, Nandi, the bull, remains the symbol of Shiva even today. The famous golden calf in the Exodus story was the bull that represented Yahweh’s arch rival, Baal. Only coincidently, however, the bull is the symbol of Wall Street, but certainly appropriate as signifying the cycle of birth, growth, decline and death. And maybe reincarnation.
