What was the role of ignatius Donnelly in popularizing the idea of a lost atlantis

Answer: "Atlantis: A Pre-Proton World".

Explanation:

It is a book that was published in 1882 and was written by Ignatius Donnelly. This work strongly popularized the story of Atlantis. The author described the submerged continent, which, according to Plato, was located outside the pillars of Heracles near Gibraltar, the strait separating the Mediterranean Sea from the Atlantic Ocean. Modern oceanography and the knowledge of tectonic plates we have today do not support this theory. Plato does provide some information about Atlantis. However, the existence of this civilization has not yet been confirmed.
