Why was the bull associated with Hadad and Teshub?

In the context of ancient Syrian and Anatolian religion, the bull was associated with the weather gods Hadad and Teshub as a symbol of their power and divine nature.12

The bull was widely revered in the ancient world as a representation of the virile principle of generation and invincible force. For weather deities like Hadad and Teshub, this animal served as a fitting emblem of their strength and authority over the natural world. The association is reflected in their iconography:312

• Symbolic Representation: The bull was the symbolic animal of both deities. In artistic depictions, Teshub is frequently shown driving a chariot drawn by bulls or standing upon one.12
• Divine Attributes: As weather gods, their power was often linked to the fertility and life-giving properties associated with rain and storms, qualities that the bull—as a symbol of virility and generative force—embodied.13
• Iconographic Motifs: Seals and other artifacts often depict a bull alone, sometimes carrying an enigmatic pyramid on its back, as a motif symbolizing the presence or power of a weather god.4
