Ideenlehre
A work in Doric Greek entitled "On the Nature of the World and the Soul" (), also called the "Timaeus Locrus" after its purported author, starts out by declaring that "Timaeus of Locri said the following" and proceeds to summarize the theories that Timaeus defends in Plato's "Timaeus". The book has been preserved fully, in more than fifty manuscripts. It is mostly consistent with Plato; it notably omits the Theory of Forms.
