In the late nineteenth-century, Charles Étienne Brasseur de Bourbourg made significant academic contributions (including re-discovery of the Popol Vuh), but towards the end of his career became convinced that the ancient Maya culture could be traced to the lost continent of Atlantis. For example, in 1857 Brasseur identified Votan as a Phoenician ruler who founded Palenque and in an article published in 1872 attributed mythological Mesoamerican cataclysms to an early version of pole shift theory. Brasseur's work, some of which was illustrated by the talented but very inaccurate Jean-Frédéric Waldeck, influenced other works of pseudoscience and pseudohistory, such as the research of Désiré Charnay, Augustus Le Plongeon, Ignatius L. Donnelly, and James Churchward.
