Timaeus

After a brief recap of the Republic, Critias introduces the legend of Atlantis, and Timaeus delivers the long monologue that gives the dialogue its name: a creation account in which a divine craftsman — the demiurge — shapes the cosmos out of necessity. The Timaeus was, for over a thousand years, the most widely read of all Plato's dialogues, and the channel through which Platonism shaped medieval and Renaissance thought.
