An augur is an individual charged with observing and interpreting omens in order to provide guidance for future events.


In Ancient Rome, the augur was a priest who interpreted the will of the gods by studying the flights of birds, one of their forms of divination, so they are most likely the Oracle of Delphi's counterpart.


Octavian, an augur

In The Son of Neptune, Octavian performs haruspication, not augury, which is divination through examining entrails of sacrificed animals performed by a haruspex. Octavian performs this through reading the entrails of stuffed animals instead of real ones.

The Heroes of Olympus

The Son of Neptune

They are mentioned when Reyna Avila Ramírez-Arellano states that after she interrogates Percy Jackson, they must consult them to decide what to do with him.
