Among all the writings of Plato the Timaeus is the most obscure to the modern reader, and has nevertheless had the greatest influence over the ancient and mediaeval world. The Critias is a fragment and it was designed to be the second part of a trilogy. Timaeus had brought down the origin of the world to the creation of man, and the dawn of history was now to succeed the philosophy of nature. It tells us about Atlantis and Critias returns to this story, professing only to repeat what Solon was told by the priests. The war of which he was about to speak had occurred 9000 years ago. One of the combatants was the city of Athens, the other was the great island of Atlantis.
