Europa is special, because it is one of the few moons in our solar system that may have liquid water. Some say that the father of this Phoenician princess was Agenor, but others say that it was Phoenix, who some claim was her brother. Her mother is unknown. Agenor was by birth an Egyptian, but he departed to Phoenicia and reigned there. If Phoenix would be considered to be the father of Europa, everything would amount to the same, because Phoenix, after whom Phoenicia is called, is said to be the son either of Agenor or of Belus, and we would, also in this way, arrive to Io.
Nothing is known about Europa's presumptive mothers.
When Zeus turned himself into a Bull, mounted Europa on his back he conveyed her through the sea from Phoenicia to Crete. However, some say that the Bull who carried Europa was the same Cretan Bull that Heracles enjoined in one of his labours, which in turn could be the same Bull, that was sent by Poseidon to King Minos of Crete, and that later, consorting with the king's wife Pasiphae, became the progenitor of the Minotaur. When Europa disappeared on the back of the Bull, Agenor sent out his sons in search of her, ordering them not to return until they had found their sister. Cilix, Europa's brother went out in his search and ended up in Cilicia in Asia Minor, a region called after him, where he became king after giving up the search. Cadmus, another of Europa's brothers, went with his mother Telephassa to Thrace and stayed there for some time, before coming to Boeotia, where he founded the city of Cadmea, which was later called Thebes.
