Zeus was the sixth child born to Cronus and Rhea. Because Cronus, ruler of the Titans and the supreme god at the time, was afraid that one of his children would overthrow him, just like he overthrew his father, Uranus, he swallowed his first five children - Poseidon, Hades, Hera, Demeter and Hestia. This made Rhea mad and when Zeus was born she tricked Cronus into swallowing a rock wrapped in blankets. Zeus is more powerful than any other god or even all the other gods combined. But, unlike many gods in other religions he was neither omnipotent nor omniscient. He could be, and in fact was, opposed, deceived and tricked by gods and men alike. His power, although great, was not boundless, Zeus had no control over The Fates and Destiny. Zeus was subject to pleasure, pain, grief, and anger, but he was most susceptible to the power of love, which often got the objects of his desire in a lot of trouble with his wife, Hera.
Zeus was carefree and loved to laugh out loud. He possessed the perfect knowledge and was just, merciful and prudent. However, he was rather unpredictable, since no one could guess the decisions he would make.
Zeus had a number of wives who bore him many children. 1. Metos (wisdom)- was his first wife and she bore Athena. 2. Themis - bore Dike, Eirene, Eunomia, Horae, and Fates. 3. Titaness - bore nine children who became the Muses. 4. Leto - bore the twins, Appolo and Artemis 5. Hera - became his permanent companion. These are not all his children and relationships they are only the main ones.
Zeus, the greatest of the Olympian gods, and the father of gods and men, was a son of Cronos and Rhea, a brother of Poseidon, Hades (Pluto), Hestia, Demeter, Hera, and at the same time married to his sister Hera. When Zeus and his brothers distributed among themselves the government of the world by lot, Poseidon obtained the sea, Hades the lower world, and Zeus the heavens and the upper regions, but the earth became common to all.
Zeus was mighty, glorious, and wise, although he did show a certain degree of surprising foolishness when it came to hiding his love affairs. Some historians attribute this less than noble behavior of the "noblest one of all" to the fact that Zeus was most likely a compilation of many "supreme gods" from different areas. When his worship spread to an area which already worshipped another god, some of that god’s qualities as well as his wife or lover were transferred to Zeus. Aside from the endless affairs Zeus was different from other gods in that he did not participate in the arguments and the resulting scheming that made up the daily activities of other gods. Being this wise ruler, he also demanded just and righteous action from men. Zeus was however vengeful, as can be seen in The creation of man by Prometheus, but only rightly so.
