Don't forget, Cholula is right beside not one but two volcanoes! In Aztec mythology, Iztaccihuatl and Popocateptl were unfortunate lovers, somewhat like Romeo and Juliet.
There are many versions of their story, but generally Iztaccihuatl was a princess who fell in love with prince Popocatepetl who was from a different tribe. Her father did not want their marriage so he agreed to it on condition that their tribe fight in a war with his troops, intending that the prince die in battle. He lied to them both, claiming the prince died in battle to his daughter and that his daughter had died of grief to the prince. Fortunately they didn't believe the lies and ran off together and lived happily, albeit briefly, together. Somehow she died and he was griefstricken and wanted to die too. (In other versions she did die before he returned and so he took her body and built a funeral altar and placed her on top; then he also lay down to die.) So the gods covered them with snow and changed them into mountains. Iztaccihuatl's mountain is called the "White Woman" because it is often white with snow and resembles a woman sleeping on her back. Beside her, his mountain is the volcano Popocatepetl, raining fire in rage at the loss of his beloved.
