Catoptromancy (Gk. κάτοπτρον, katoptron, "mirror," and μαντεία, manteia, "divination"), also known as captromancy or enoptromancy, is divination using a mirror.
Pausanias, an ancient Greek traveler, described as follows:
Before the Temple of Ceres at Patras, there was a fountain, separated from the temple by a wall, and there was an oracle, very truthful, not for all events, but for the sick only. The sick person let down a mirror, suspended by a thread till its base touched the surface of the water, having first prayed to the goddess and offered incense. Then looking in the mirror, he saw the presage of death or recovery, according as the face appeared fresh and healthy, or of a ghastly aspect.
In Ancient Rome, the priests who used catoptromancy were called speculari.
