As a Celtic Symbol meaning, the feather was worn by Druids in the form of ornate feathered robes. Celtic Druids donned these robes in ceremonies to invoke the sky gods and gain knowledge of the celestial realm. It was believed that the feathered cloak along with the presence of the sky gods would allow the Druid to transcend the earthly plane and enter the ethereal realm.
The Egyptians believed that feathers were symbolic of sky gods too. Ma'at, the Egyptian goddess of justice, would weigh the hearts of the newly dead in the underworld against the weight of a feather to determine the worthiness of his or her soul.
In Christianity feathers represented virtues. In fact, an image of three feathers were made into signet rings - each feather symbolizing Charity, hope, and faith. These rings were worn as a symbol of a virtuous soul - they were also used as wax seals. The ring would be dipped in warm wax then pressed against documents to seal the closure. The recipient would know the documents came from a virtuous man by the indication of the three-feather symbol in the wax.
