Uromancy is a form of divination, by reading the bubbles in urine that form when urinating in a pot.
Its origin can be found in medicine, where uroscopy, the examination of urine, is used as a diagnostic tool. In uromancy it is said that the urine does not only give indications of a person's health, but also foretells the future.
The suffix mancy originates from the ancient Greek word manteia, which means divination.
