Thousands of years ago many people believed in a god named Zeus. He was considered to be the god of the sky and weather and his image appeared on most Greek coins. The people of Greece worshipped this idol as their god.
Zeus was the supreme god and ruler of Olympus. He was known by many titles: Lord of the Sky, the Cloud- gatherer, the Rain-god and Zeus the Thunderer, all of which show which force of nature was considered to be the most important in Ancient World - rain.
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, of course, infuriated Rhea and when Zeus was born she tricked Cronus into swallowing a rock wrapped in blankets.
