Augury is an ancient form of divination. The practice was performed in ancient
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
Amongst the most remarkable of natural occurrences must be included many of the phenomena connected with the behaviour of birds. Undoubtedly numerous species of birds are susceptible to atmospheric changes (of an electrical and barometric nature) too slight to be observed by man's unaided senses; thus only is to be explained the phenomenon of migration and also the many other peculiarities in the behaviour of birds whereby approaching changes in the weather may be foretold. Probably, also, this fact has much to do with the extraordinary homing instinct of pigeons.
But, of course, in the days when meteorological science had yet to be born, no such explanation as this could be known. The ancients observed that birds by their migrations or by other peculiarities in their behaviour prognosticated coming changes in the seasons of the year and other changes connected with the weather (such as storms, etc.); they saw, too, in the homing instincts of pigeons an apparent exhibition of intelligence exceeding that of man.
What more natural, then, for them to attribute foresight to birds, and to suppose that all sorts of coming events (other than those of an atmospheric nature) might be foretold by careful observation of their flight and song?
Augury was extensively cultivated by the Etrurians and Romans. It is still used by the natives of
The augurs were consulted on all matters of importance, and the position of augur was thus one of great consequence. In what appears to be the oldest method, the augur, arrayed in a special costume, and carrying a staff with which to mark out the visible heavens into houses, proceeded to an elevated piece of ground, where a sacrifice was made and a prayer repeated. Then, gazing towards the sky, he waited until a bird appeared. The point in the heavens where it first made its appearance was carefully noted, also the manner and direction of its flight, and the point where it was lost sight of. From these particulars an augury was derived, but, in order to be of effect, it had to be confirmed by a further one.
