In Greco-Roman mythology the Peacock

In Greco-Roman mythology the Peacock is identified with the goddess Hera (Juno). The eyes upon the peacock's tail comes from Argus whose hundred eyes were placed upon the peacock's feathers by the goddess in memory of his role as the guard of Io, a lover of Zeus that Hera had punished. The eyes are said to symbolize the vault of heaven and the "eyes" of the stars.
In Hinduism, the Peacock is associated with Saraswati, a deity representing benevolence, patience, kindness, compassion and knowledge. Similar to Saraswati, the Peacock is associated with Kwan-yin in Asian spirituality. Kwan-yin (or Quan Yin) is also an emblem of love, compassionate watchfulness, good-will, nurturing, and kind-heartedness. Legend tells us she chose to remain a mortal even though she could be immortal because she wished to stay behind and aid humanity in their spiritual evolution.
In Babylonia and Persia the Peacock is seen as a guardian to royalty, and is often seen in engravings upon the thrones of royalty.

In Christianity, the peacock is an ancient symbol of eternal life.[3] The Peacock symbolism represents the "all-seeing" church, along with the holiness and sanctity associated with it. Additionally, the Peacock represents resurrection, renewal and immortality within the spiritual teachings of Christianity. Themes of renewal are also linked to alchemical traditions to, as many schools of thought compare the resurrecting phoenix to the modern-day Peacock.


Melak Ta’us, the Yazidi Peacock Angel
Melek Taus (ملك طاووس - Kurdish Tawûsê Melek), the Peacock Angel, is the Yazidi name for the central figure of their faith. The Yazidi consider Tawûsê Melek an emanation of God and a benevolent angel who has redeemed himself from his fall and has become a demiurge who created the cosmos from the Cosmic egg. After he repented, he wept for 7,000 years, his tears filling seven jars, which then quenched the fires of hell. In art and sculpture, Tawûsê Melek is depicted as a peacock. However, peacocks are not native to the lands where Tawûsê Melek is worshipped.
In 1956, John J. Graham created an abstraction of an eleven-feathered peacock logo for American broadcaster NBC. This brightly hued peacock was adopted due to the increase in color programming. NBC's first color broadcasts showed only a still frame of the colorful peacock. The emblem made its first on-air appearance on May 22, 1956.[4] The current version of the logo debuted in 1986 and has six feathers (yellow, orange, red, purple, blue, green).
