Voltaire (1694-1778) was the pen-name of François-Marie Arouet, who was born in Paris and became one of France’s best known philosophers. He wrote prolifically on a wide range of subjects with an estimated output of more than 2,000 books and pamphlets and 20,000 letters.

I am only aware of one reference by him to Atlantis in The Philosophy of History (1765), in which he  suggested Madeira as the most likely location of Plato’s island.

Anyone researching Atlantis might be advised to remember Voltaire’s aphorism which states that while “doubt is not a pleasant mental state, certainty is an absurd one.”
