Here is something strange -- The swan symbol and an Apollo tie-in :
From :APOLLO
When Apollo entered the world, sacred swans circled the island seven times for it was the seventh day of the month. At once Zeus lavished many gifts upon his son including a golden miter, a chariot drawn by swans, and a lyre since legend has it at birth Apollo said, "Dear to me shall be the lyre and bow, and in oracles I shall reveal to men the inexorable will of Zeus." The god commanded his so to find sanctuary at Delphi. But before taking Apollo to Delphi, the swans flew him north to their own country on the edge of the ocean, which was home to the Hyperborean people, who was a supremely happy race for whom life was sweet. When the elderly became weary of existence, they accepted voluntary death by throwing themselves into the sea. Apollo was their high god; and went there at certain times to receive their homage. So, following his birth, he remained there an entire year before returning to Greece and reaching Delphi in midsummer. Nature made herself the most beautiful for him. Annually, the arrival of the god was celebrated with solemn ceremony and great slaughter.
