Please study the Sacred Peacock and its closest relatives, the Phoenix, Quetzal, Golden Pheasant, Mediterranean or Persian Cockerel etc., which were sacred and propagated around the World by the Devotees of the Supreme Lord. Some of them Heralded the Dawn, and were thus widely revered for their sensitivity to the first light of the day. The Peacock and Persian or Domestic Cock (Rooster, see Wiki) were both important in Judaism, and in the Schools devoted to Asclepios Iasas (Jesus, Ananta-Charaka) the Great Physician.
The most familiar Peacock itself was imported from India by the Bible’s King Solomon (Jewish Scriptures [Christian Old Testament], Kings 10:22, 2 Chron. 9:21), and was the Symbol of the Royal Messianic Lineage of David. Scholars have long recognized that the ancient Biblical word for Peacock comes from Tamil Nadu South India.
