Kriton

The Critias is a fragment which breaks off in the middle of a sentence. It was designed to be the second part of a trilogy, which, like the other great Platonic trilogy of the Sophist, Statesman, Philosopher, was never completed. 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. The Critias is also connected with the Republic.
