Ornithomancy (modern term from Greek ornis "bird" and manteia "divination"; in Ancient Greek: οἰωνίζομαι "take omens from the flight and cries of birds") is the practice of reading omens from the actions of birds followed in many ancient cultures including the Greeks, and is equivalent to the augury employed by the ancient Romans.

Ornithomancy in some form has been found globally among a wide variety of pre-industrial peoples.[1]

Mediterranean developments

Prophesying by birds appeared among the Hittites in Anatolia, with texts on bird oracles written in Hittite known from the 13th or 14th century BCE,[2] and from whom the Greek practice may derive.[3] It was also familiar to the Etruscans, who may have brought it to Rome.[4]

Greek evidence

Ornithomancy dates back to early Greek times, appearing on Archaic vases, as well as in Hesiod and Homer:[5] one notable example from the latter occurs in the Odyssey, when an eagle appears three times, flying to the right, with a dead dove in its talons, an augury interpreted as the coming of Odysseus, and the death of his wife's suitors. Aeschylus has Prometheus claim to have introduced ornithomancy to mankind, by indicating among the birds “those by nature favourable, and those/Sinister”.[6]

Ornithomancy could be spontaneous, or it could be the result of a formal consultation:[7] the seer would face north, and birds on their right—the east, the direction of sunrise—were taken as favourable (the reverse being true of the Roman augur, who by contrast faced south).[8] Although it was mainly the flights and songs of birds that were studied, any action could have been interpreted to either foretell the future or relate a message from the gods.

Roman practice

Main article: Augur

Omens from observation of the flight of birds were considered with the utmost seriousness by Romans. The practice of ornithomancy by priests called augurs was a branch of Roman national religion from before the founding of the city, which had its own priestly college to supervise its practice.[9]

The word "inauguration" is derived from the Latin noun inauguratio derived from the verb inaugurare which was to "take omens from birds in flight." Since Roman augurs predominantly looked at birds for omens, they were also called auspex ("bird watcher", plural auspices), however they also interpreted thunder, lightning, the behavior of certain animals, and strange events. The phrase "under the auspices" is derived from this need for a favourable reading of the omens by the augurs.[10][11]

Cultural echoes

Other examples

One of the black bird sculptures of Taivoan people in the Public Hall Kong-kài in Rauron.


The Taivoan people refer to the 'oh-ah, oh-ah' call of crows as pháinn-kiat-tiāu, signifying an omen of bad luck and could also indicate an impending attack by other indigenous communities. Hunters are advised not to leave for hunting if they heard such a call. The black bird sculptures, commonly seen on the roofs of the Public Hall Kong-kài in Taivoan communities like Rauron, are believed to represent crows.[14]
