The question of Plato, as the primary and universally known and recognized profane source regarding the mention of Atlantis, its history, its description and its tragic end, necessarily deserves some reflections, considerations and insights, since, in the vast bibliography concerning this argument, the Athenian philosopher is always and punctually called into question, both by supporters of the past existence of the lost continent, and by skeptics, detractors and deniers of its existence. But Plato was certainly not the first ancient author to mention Atlantis. Many others did it before him, although their works have been lost. In ancient Greece and in all the civilizations of the Mediterranean and the Near East no cultured person doubted the real historical existence of the mythical lost continent. Likewise, the memory of a terrible catastrophe that changed the face of our planet, annihilating all previous forms of civilization, has remained imprinted in the collective memory, in the myths and legends of all peoples. The historian and essayist Nicola Bizzi, with this new work, sheds new light on one of the greatest secrets of our past.
