"Popocatépetl and Iztaccíhuatl" refers to a number of mythical and folkloric explanations of the origins of the volcanoes Popocatépetl ("the Smoking Mountain") and Iztaccíhuatl ("white woman" in Nahuatl, sometimes called the Mujer Dormida "sleeping woman" in Spanish) which overlook the Valley of Mexico. The most common variety relates the Nahua romance of the princess Iztaccíhuatl and the warrior Popocatépetl. This tale is recorded in several different versions.
A summary based on one version as recounted at a September 2006 "Myth, Mortals and Immortality: Works from the Museo Soumaya de México" exhibition at the Smithsonian Institution.
