Timaeus and Critias is a Socratic dialogue in two parts. A response to an account of an ideal state told by Socrates, it begins with Timaeus’s theoretical exposition of the cosmos and his story describing the creation of the universe, from its very beginning to the coming of man. Timaeus introduces the idea of a creator God and speculates on the structure and composition of the physical world. Critias, the second part of Plato’s dialogue, comprises an account of the rise and fall of Atlantis, an ancient, mighty and prosperous empire ruled by the descendents of Poseidon, which ultimately sank into the sea.

Taking the form of dialogues between Socrates, Timaeus, Critias and Hermocrates, these two works are among Plato's final writings. In Timaeus, he gives a thorough account of the world in which we live, describing a cosmos composed of four elements - earth, air, fire and water - which combine to give existence to all things. An exploration of the origins of the universe, life and humanity, which outlines not just physical laws but also metaphysical and religious principles, it remained a paradigm of science for two thousand years. The mysterious preamble to Timaeus contains the first account in literature of Atlantis, while the fragmentary Critias, unfinished by its author, provides a spellbinding description of the lost continent's ideal society, which Critias asserts was created by the god-like children of Poseidon himself.

'The god wanted everything to be good, marred by as little imperfection as possible.' Timaeus, one of Plato's acknowledged masterpieces, is an attempt to construct the universe and explain its contents by means of as few axioms as possible. The result is a brilliant, bizarre, and surreal cosmos - the product of the rational thinking of a creator god and his astral assistants, and of purely mechanistic causes based on the behaviour of the four elements. At times dazzlingly clear, at times intriguingly opaque, this was state-of-the-art science in the middle of the fourth century BC. The world is presented as a battlefield of forces that are unified only by the will of God, who had to do the best he could with recalcitrant building materials. The unfinished companion piece, Critias, is the foundational text for the story of Atlantis. It tells how a model society became corrupt, and how a lost race of Athenians defeated the aggression of the invading Atlanteans. This new edition combines the clearest translation yet of these crucial ancient texts with an illuminating introduction and diagrams.
