Popocatépetl and Iztaccíhuatl
Popocatépetl and Iztaccíhuatl refers to the volcanoes Popocatépetl ("the Smoking Mountain") and Iztaccíhuatl ("White (like salt) woman" in Nahuatl, sometimes called the Mujer Dormida "sleeping woman" in Spanish) in Iztaccíhuatl–Popocatépetl National Park, which overlook the Valley of Mexico and the various myths explaining their existence. The most common variety relates the Nahua romance of the princess Iztaccíhuatl and the warrior Popocatépetl. This tale is recorded in several different versions.
