Throughout the Near East and the Aegean, including in Mesopotamia, Crete, Greece and Canaan, the son-god was often represented as a young bull or calf, which was natural since the Great Mother was associated with the cow. The process of death and rebirth was reenacted in annual rituals in which the bull (son) was slain and sacrificed so it could return to the Great Mother for rebirth and so the growing season could successfully begin anew. Another animal that acquired this meaning was the serpent, since serpents are chthonic creatures that hibernate in the winter and reappear in the spring when the plants come alive.
