Paul Borchardt (1886-1953) was a German archaeologist, a pupil of the geographer Siegfried Passarge. He is known for his theory that the mythical city of Atlantis was located in Tunisia. Borchardt argued that the Shott el Jerid swamp, generally thought to mark the site of Lake Tritonis, was in fact the original Atlantic Sea referred to by Plato. Borchardt also identified Mount Atlas as being a peak in the Ahaggar Mountains, rather than in the Atlas range. He related the names of Berber tribes to the names of Poseidon's sons in Greek mythology, and suggested links between the city of Atlantis, the palace of Alkinoös referenced in The Odyssey and the City of Brass in the tales of The Arabian Nights. He believed he had discovered Atlantean ruins at Qabes, but these ruins were later found to be of Roman origin.
