Two late dialogues of Plato designed to be part of a trilogy that the philosopher did not finish, "Timaeus" and "Critias" utilize a few select men to theorize on the natural world and to tell a story of the lost city of Atlantis. Critias is one of Plato's late philosophical dialogues and the second part of his planned trilogy about the battle between the mythical island of Atlantis and Athens which according to legend took place 9000 years before Plato's time.. Critias begins by describing the Athenian society of 9000 years before their time as an ideal society. In the former, Plato describes how Egyptian priests, in conversation with the Athenian lawgiver Solon, described Atlantis as an island larger than Asia Minor and Libya combined, and situated just beyond … Together the dialogues are a festival speech, prepared by Plato to be told on the day of the Panathenaea, in honor of the goddess Athena. According to the dialogues, Socrates asked three men to meet him on this day: Timaeus of Locri, Hermocrates of Syracuse, and Critias of Athens. The principal sources for the legend are two of Plato ’s dialogues, Timaeus and Critias. he had finished this dialogue remains an interesting speculation. . The fact is, that wherever the extremity of winterfrost or of summer sun does not prevent, the human race is increasing at times, at other times diminishing in numbers. 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. For unknown reasons, Plato never completed Critias. When Atlantis attacked, Athens showed its excellence as the leader of the Greeks, the much smaller city-state the only power to stand against Atlantis. Some of the strongest arguments in favor of the Thera theory of Atlantis come from two dialogues written by Greek philosopher Plato. From Plato's Timaeus and Critias. Timaeus of Locri, in real life, may have been a Pythagorean philosopher of the 5th century B.C. . For these histories tell of a mighty power which was aggressing wantonly against the whole of Europe and Asia, a power to which your city put an end. And he named them all; the eldest, who was king, he named Atlas, and from him the name Atlantic was applied to the whole island and the neighboring ocean.... Now Atlas had a numerous and honorable family, and his eldest branch always retained the kingdom, which the eldest son handed on to his eldest for many generations; and they had such an amount of wealth as was never before possessed by kings and potentates, and is not likely ever to be again, and they were furnished with everything they could have both in city and in country. His works Timaeus and Critias, written around the 350’s B.C., used the debates and conversations of characters to discuss and reveal the thinker’s own thoughts and discoveries about the ancient civilization. N.S. . Timaeus describes the creation of the world and explains natural phenomena while Critias talks of a lost island, its people and ancient Athenians. Taking the form of dialogues between Socrates, Timaeus, Critias and Hermocrates, these two works are among Plato's final writings. . There have been and will be again, many destructions of mankind arising out of many causes; the greatest have been brought about by the agencies of fire and water, and other lesser ones by innumerable other causes. Alone, Athens triumphed over the invading Atlantean forces, defeating the enemy, preventing the free from being enslaved, and freeing those who had been enslaved. The palaces in the interior of the citadel were constructed in this wise: In the center was a holy temple dedicated to Cleito and Poseidon, which remained inaccessible, and was surrounded by an enclosure of gold; this was the spot in which they originally begat the race of ten princes, and thither the people annually brought the fruits of the earth in their season from all the ten portions, and performed sacrifices to each of them. Solon marveled at this and earnestly requested the priest to inform him exactly and in order about these former citizens.
