What term best describes the priests who predicted future events through divination?

The term that best describes the priests who predicted future events through divination is "Augures." In ancient Rome, Augures were specialized priests responsible for interpreting the will of the gods by observing the flight patterns of birds and other omens. Their primary function was to provide insights that influenced important state decisions and military actions, signifying their vital role in both religious and civic life.

The Augures' practice included reading signs from nature, especially through avian omens, which they believed could forecast future events and outcomes. This interpretation was crucial for leaders before making significant moves, thereby linking divination closely to political and military strategy in Roman culture.

Other terms mentioned have distinct functions within Roman religion and society. Salii were priests dedicated to the worship of Mars and were primarily involved in rituals rather than divination. Fetiales were involved in diplomatic matters and the declaration of war, focusing more on legal and ceremonial tasks than on predicting the future. Flamines were priests assigned to specific deities and conducted regular sacrifices, but their role did not center around divinatory practices. Thus, "Augures" is the most accurate term associated with the practice of predicting future events through divination.
