Mnemosyne the Greek goddess of the mind is suddenly invoked in Critias (108d) to assist with the recollection of the details of the Atlantis story. This has been seen by some as being in conflict with Plato’s explicit statement Critias (113b) that he was working from Solon’s written notes. Plato was advancing in years when he wrote Critias, so when he declares that as a child he memorised the names of the first kings of Atlantis it is quite natural that he expressed the hope that his memory was still reliable.
