It’s related to main shape of Viking age jewellery. Majority of known rings, bracelets and torques of the period have snake or serpent design. For Norse art expert it’s not possible at all to answer why all people man and women and kids wore same type of the rings? Viking elite silver and gold and poor people and kids in bronze but everyone had one. It is clear what it was not related to fashion and what is also interesting that “snake” ring and other jewellery design disappeared after Norse people adopted Christianity as main religion.

To answer this question correctly, we should understand the roots of Pagan beliefs of Norse people. And it’s really old story. The first European Gods figurines carved in stone and woolly ammoth tusk usually dated 30.000 BC. The cult of Mother Goddess in Europe and its high level of acceptance by early  European farmers can be dated 7-2 Millennium BC.

It is confirmed that snake symbol was one of the main symbols of Mother Goddess – it’s symbol of life, birth, death and rebirth. Its one of the infinity symbols and that is important for our study – its Symbol of protection. The “Good snake” is home protector as per our ancestors early Pagans beliefs. We understand that in grain storages, Old Europe farmers were keeping snakes to save the crop from rodents during long winters and it was crucial for  human beings to survive.
