Mythology and History

Pavo is a constellation that first appeared on a star map by Johann Bayer in 1603. He probably took it over from the seafarers of the 16th century. The constellation belongs together with Apus, Tucana, Grus and Phoenix to the "heavenly" birds.

In Greek mythology, the peacock was dedicated to the goddess of the sky (Hera). According to legend, Hera had commissioned the hundred-eyed Argus to watch out for a white cow, in whose shape she assumed one of the countless lovers of her godly husband Zeus: the nymph Io. Zeus sent Hermes, who cut off Argus' head and thus freed the cow. To do this, Hera moved Argus' hundred eyes to the peacock's tail. [7, 21]
