The Augur (pl: augurs) was a priest and official in the classical world, especially ancient Rome. His main role was to interpret the will of the gods by studying the flight of the birds (flying in groups/alone, what noises they make as they fly, direction of flight and what kind of birds they are), known as "taking the auspices." The ceremony and function of the augur was central to any major undertaking in Roman society--public or private--including matters of war, commerce, and religion.Consider the words of the Roman historian Livy, who writes (VI.41): auspiciis hanc urbem conditam esse, auspiciis bello ac pace domi militiaeque omnia geri, quis est qui ignoret? ("Who does not know that this city was founded only after taking the divinations, that everything in war and in peace, at home and abroad, was done only after taking the divinations?")
