Peacock feathers are considered evil by Greek, Romans and Egyptians most probably due to the Greek myth that associated the peacock plumage with the monster eyes of Argus, who was the loyal servant of Greek Goddess Hera. However, it appears that peacocks represent rebirth, renewal and life in Christianity. There is also a belief linked to this which says peacocks have the power to dispel evils. Many ancient paintings and other art works show peacock feathers in the four wings of angels.
White peacock is always a symbol of purity.
Peacocks are seen as symbols of royalty and elegance in many cultures, especially in Southeast Asia and the monarchs used the feathers of peacocks mostly in hair accessories or hand fans as a symbol of royalty. Green peafowls were once very common in countries like Thailand, Indonesia and Burma and many Burman monarchs considered these peacocks as a symbol of their royalty.
Peacocks have always been a subject of paintings and other art works, including pottery and stoneworks, and also literature and poetry. Blue peacocks or the Indian peafowls are native to the Indian subcontinent and peacock designs in the traditional dresses and jewelry are very popular in India. The presence of a peacock is also considered very sacred and auspicious in India and it is linked to the presence of God itself.
Peacocks are also the guardians of paradise, according to the beliefs in many ancient cultures.
