\Ca*top"tro*man`cy\, n. [Gr. ? mirror + -mancy.
See {Catopter}.] (Antiq.)
A species of divination, which was performed by letting down
a mirror into water, for a sick person to look at his face in
it. If his countenance appeared distorted and ghastly, it was
an ill omen; if fresh and healthy, it was favorable.
