In Greek mythology, Thesis embodies Metis, the goddess of wisdom, who was famously swallowed whole by Zeus. In this narrative, however, she is portrayed as Zeus's lover, with whom he has a daughter named Childanope.

Zeus, the king of the gods and the deity of the sky, weather, law and order, destiny, and kingship, rules over a realm called Simanity. In this story, he is depicted as an immortal god deeply infatuated with Eve, a mortal woman. Their union results in the birth of a child named Physis. Despite his profound love for Eve, Zeus engages in affairs with other deities as a form of rebellion against powerful gods who forbid him from pursuing his love for her. Among these encounters is his relationship with Thesis, whom he uses for revenge and ultimately impregnates.

In classical mythology, Childanope (Ancient Greek: Χλιδανώπης) is recognized as the naiad wife of King Hypseus of the Lapiths and the daughter of the river-god Peneus. Together, they have four daughters: Cyrene, Themisto, Alcaea, and Astyagyia. Within the context of Simanity, she is reimagined as the love child of Zeus and Thesis.
