When did Plato write his Timaeus and Critias?
Plato lived between 427-347 BC and is believed to have written the Timaeus and Critias after the death of his friend Socrates in 399 BC. Some discussion exists – as is often the case with ancient texts – regarding the dual authorship of the Timaeus and Critias. However lack of any real consensus has left the whole question in the air.
