The use of mirrors in Mesoamerican culture was associated with the idea that they served as portals to a realm that could be seen but not interacted with. Mirrors in pre-Columbian Mesoamerica were fashioned from stone and served a number of uses, from the decorative to the divinatory. An ancient tradition among many Mesoamerican cultures was the practice of divination using the surface of a bowl of water as a mirror. At the time of the Spanish conquest this form of divination was still practiced among the Maya, Aztecs and Purépecha. In Mesoamerican art, mirrors are frequently associated with pools of liquid; this liquid was likely to have been water.
