And then you have the Chac Mool, Mezoamerican god of rain and lightning. Mool is pronounced with an accented long o and almost swallowing the l. Chac Mool was the god that figured prominently in human sacrifice. The sacrificial victim would lie on Chac's belly, face to the sky, while the priest cut out his/her heart with an obsidian knife.
