Augury is an ancient form of divination. The practice was performed in ancient Rome by priests called augurs. It entailed the interpretation of auspices, that is the movement of birds and/or the movement of animals. Also included in this form of divination was the interpretation of the significance of thunder and lightening. Those signs on the augur’s left or east side denoted a favorable outcome, while those on the right pointed to an ill-omen. This method of divination was practically unknown in ancient Mesopotamia and Palestine.
