Divination.
Divination (Greek μαντεια, from μαντις "seer", anglicized in the suffix -mancy, see also mania) is the attempt of ascertaining information by interpretation of omens or an alleged supernatural agency.

If a distinction is to be made between divination and fortune-telling, divination has a formal or ritual and often social character, usually in a religious context; while fortune-telling is a more everyday practice for personal purposes. Divination is often dismissed by skeptics, including the scientific community, as being mere superstition: in the 2nd century, Lucian devoted a witty essay to the career of a charlatan, Alexander the false prophet, trained by "one of those who advertise enchantments, miraculous incantations, charms for your love-affairs, visitations for your enemies, disclosures of buried treasure, and successions to estates" , though most Romans believed in dreams and charms. Advocates of divination will usually cite a mass of anecdotal evidence for the efficacy of divination.

Divination is a universal cultural phenomenon which anthropologists have observed as being present in many religions and cultures in all ages up to the present day.
