The white stag was a common symbol in European folklore, making an appearance in many different cultures and legends.
The Celtic people considered them to be prophets, messengers of different worlds. White stags heralded purity, as the colour white is often associated with immaculacy and beauty. It was said that when a white stag appeared, it foreshadowed the coming of great change. They have been described as being radiant and acquiring a human-like intelligent unprecedented in other creatures.
There was a Hungarian legend, the tale of Hunor and Magor, where a white stag aided the men in discovering a rich, prosperous land in which they settled.
However, a strict contrast to the Hungarian tale, in Finland the white stag is perceived as being a creature of the underworld and often hypnotized hunters with its appearance before inevitably leading them to their death.
Scandinavian peoples and those surrounding them were SUPER SUPERSTITIOUS. If it was out of the ordinary SHIT RUN PROBABLY FROM THE UNDERWORLD.
