White Stag/ Deer/ Elk... The Native Americans believed the occurance of a white animal was a huge sign of prophecy – a sign from the great spirit that a major shift in their world was to come. Usually, white animals were seen during soul-quests, or vision-quests. When white occurs in the animal realm it is a message of higher thoughts, higher ideals, purity of soul, cleansing of spirit and attaining higher knowledge.
For the ancient Celts, the white hart was a harbinger of doom, a living symbol that some taboo has been transgressed or a moral law broken. The white hart's reputation improved in Arthurian legends, where its appearance was a sign to Arthur and his knights that it was time to embark on a quest - it was considered the one animal that could never be caught so it came to symbolise humanity's never-ending pursuit of knowledge and the unattainable.
