Callisto (mythology) VS Alkonost

Callisto (mythology)
In Greek mythology, Callisto or Kallisto (; Ancient Greek: Καλλιστώ [kallistɔ̌ː]) was a nymph, or the daughter of King Lycaon; the myth varies in such details. She was one of the followers of Artemis, or Diana for the Romans, who attracted Zeus (Jupiter). According to some writers, Zeus transformed himself into the figure of Artemis to lure Callisto and seduce her. She became pregnant and when this was eventually discovered, she was expelled from Artemis's group, after which a furious Hera (Juno), the wife of Zeus (Jupiter), transformed her into a bear. Later, just as she was about to be killed by her son when he was hunting, she was set among the stars as Ursa Major ("the Great Bear"). She was the bear-mother of the Arcadians, through her son Arcas by Zeus. The fourth Galilean moon of Jupiter and a main belt asteroid are named after Callisto.

Alkonost
The Alkonost is, according to Russian mythos and folklore, a woman-headed bird. It makes amazingly beautiful sounds, and those who hear these sounds forget everything they know and want nothing more ever again. She lives in the underworld with her counterpart, the Sirin. The Alkonost lays her eggs on a beach and then rolls them into the sea. When the Alkonost's eggs hatch, a thunderstorm sets in and the sea becomes so rough that it becomes impossible to traverse. She is also the sister of other birds from Slavic mythology, such as Rarog and Stratim.According to folk tales, at the morning of the Apple Feast of the Saviour day, Sirin flies into the apple orchard and cries sadly. In the afternoon, the Alkonost flies to this place, beginning to rejoice and laugh. Alkonost brushes dew from her wings, granting healing powers to all fruits on the tree she is sitting on.The name of the Alkonost came from a Greek demigoddess whose name was Alcyone. In Greek mythology, Alcyone was transformed by the gods into a kingfisher.Alkonost is more likely an individual character, as was noted in some legends about this bird.
