Ancient Greeks. In 2008, researchers said a reference to a total eclipse was found in Homer's Odyssey, with the lines The sun has perished out of heaven, and an evil mist has overspread the world. The Ancient Greeks believed a total eclipse to be a bad omen.
Later scientists called Aristotle the Father of Natural Science because centuries after the ancient scholar's death, his methods formed the basis of the scientific method. Most people in Aristotleâs time believed the earth was flat, but he did not agree. The Greek thinker realized that a lunar eclipse occurred when the earth came between the sun and the moon. The shape of the earthâs shadow, Aristotle observed, was round. If the earth were flat, its shadow would have a much different form. Next, Aristotle considered the position of the North Star. The farther north you journeyed, the closer the North Star seemed to move to the middle of the sky.
