Гректің мифологиясындағы Зевстің сүйіктісі Ио

Mortal woman seduced by Zeus in Greek mythology
Io ('/aɪ//.//oʊ/; Ἰώ ) was, in Greek mythology, one of the mortal lovers of Zeus. An Argive princess, she was an ancestor of many kings and heroes, such as Perseus, Cadmus, Heracles, Minos, Lynceus, Cepheus, and Danaus. The astronomer Simon Marius named a moon of Jupiter after Io in 1614. Because her brother was Phoroneus, Io is also known as Phoronis (an adjective form of Phoroneus: "Phoronean"). She was sometimes compared to the Egyptian goddess Isis, whereas her Egyptian husband Telegonus was Osiris.

In most versions of the legend, Io was the daughter of Inachus, though various other purported genealogies are also known. If her father was Inachus, then her mother would presumably have been Inachus' wife (and sister), the Oceanid nymph Melia, daughter of Oceanus, although this is nowhere stated. Io's father was called Peiren in the Catalogue of Women, and by Acusilaus, possibly a son of the elder Argus, also known as Peiras, Peiranthus or Peirasus. Io may therefore be identical to Callithyia, daughter of Peiranthus, as is suggested by Hesychius of Alexandria. The 2nd century AD geographer Pausanias mentions another, later Io, descendant of Phoroneus, daughter of Iasus, who himself was the son of Argus and Ismene, the daughter of Asopus, or of Triopas and Sosis; Io's mother in the latter case was Leucane.

Lygdus and his wife, Telethusa, were a poor couple living in Crete. When Telethusa became pregnant, her husband told her that they can't afford having a daughter, and that they have no other option than to kill the child if it would be a daughter. 8 months later Io, later in the story mentioned as Isis, came in a vision to Telethusa telling her that she should keep her daughter when it's born and must tell her husband that it's a boy named Iphis. Later in the story, Isis (Io) changes Iphis' sex when she is supposed to marry her fiancée, Ianthe.
