How did the ancient astronomers pictured the Universe?

The ancient astronomers pictured the Universe from the point of view of an observer on Earth. In fact, to them, the Earth was the centre of the Universe, and they believed that above it was a shining dome that was sprinkled with thousands of shining little lights that were the Sun, the Moon and the stars.

Later, the Greek astronomer Pythagoras suggested that the Earth might be a sphere, but he still thought that it was the centre of the Universe. It was only in 1543 that an astronomer named Copernicus suggested that the Sun might be the centre of the Universe. It was with the discovery of the telescope that Man finally developed a better picture of what the Universe is really like.
