5.1 The Story Behind Pavo
Pavo, commonly known as The Peacock, is a constellation in the southern hemisphere that possesses a fascinating story behind its name. In Greek mythology, the origins of Pavo are connected to a famous goddess named Hera. According to the myth, Hera had a servant named Argus Panoptes, who had one hundred eyes. Hera tasked Argus with the duty of guarding a special cow named Io, who was one of Zeus’ lovers in disguise. However, Zeus, fearing Hera’s wrath, transformed Io into a beautiful white heifer to protect her. Angered by the turn of events, Hera sent a malicious fly called “stinging gadfly” to torment Io and ensure her continued misery.
As Io wandered the earth in distress, her path led her to the region known as Pavo. It was here that she came across the shepherd king, Argus, who had been chosen by Hera to watch over Io. However, Io’s path also caught the attention of Zeus, who felt sympathy for her plight. In an attempt to rescue Io, Zeus sent his messenger god, Hermes, to slay Argus and free Io from her torment. Hermes accomplished this by lulling Argus to sleep with his enchanting music before delivering a fatal blow. Upon Argus’ death, Hera immortalized him by placing his one hundred eyes on the tail of a peacock, which she deemed one of the most beautiful creatures in the world.
And thus, Pavo, with its striking shape resembling a peacock with its tail fanned out, became associated with this mythological tale.
