Thor is the Norse hammer-wielding god associated with thunder, lightning, storms, oak trees, strength, destruction, fertility, healing, and the protection of mankind. Mjolnir is the name of his hammer, the most fearsome weapons, capable of levelling mountains. The Prose Edda revealed that if thrown, Mjolnir would always return to Thor’s grasp and “when he wanted, it would be so small that it could be carried inside his tunic.” A2 size, photo quality.
