Jacques Hébert is the author of Atlantide: La Solution Oubliee concerning Atlantis. As a former Parisian police chief, he claims to have applied his skills in that field to solving the mystery of Plato’s island. He critically re-examines the original text and offers an interpretation that he believes provides a more rational and harmonious reading of the narrative. His conclusion is that Atlantis lay in the Indian Ocean and that its culture was derived from the Indus valley. He specifically identifies the Yemeni island of Socotra as part of the Atlantean civilisation
Hébert identifies Bab el Mandeb as Plato’s Pillars of Heracles, by assuming that Solon mistook the description of that strait, given to him by the priests of Sais, with the Strait of Gibraltar, which has similar features. The earthquake that destroyed Atlantis is attributed by him to a close encounter with an extraterrestrial body.
