;ex avibus [
from birds]: Though auspices were typically bird signs, not all birds in the sky were seen as symbols of the will of the gods. There were two classes of birds:
Oscines, who gave auspices via their singing; and
Alites, who gave auspices via how they flew. The Oscines included ravens, crows, owls and hens, each offering either a favorable omen (
auspicium ratum) or an unfavorable depending on which side of the Augur's designated area they appeared on. The birds of the Alites were the eagle, the vulture, the
avis sanqualis, also called
ossifraga, and the
immussulus or
immusculus. Some birds like the
Picus Martius, the
Feronius, and the
Parrha could be considered among the oscines and the alites. Every movement and every sound made by these birds had a different meaning and interpretation according to the different circumstances, or times of the year when it was observed. ;ex tripudiīs [
from the "dance" (of birds feeding)]: These auspices were read by interpreting the eating patterns of chickens, and were generally used on military expeditions. Cicero shows that at one point, any bird could perform the
tripudium [sacred dance], but that as the practice progressed it soon began customary to use only chickens. The chickens were kept in a cage under the care of the
pullarius (keeper of the chickens) who, when the time came, released the chickens and threw at them some form of bread or cake. If the chickens refused to come out or eat, or uttered a cry, or beat their wings, or flew away, the signs were considered unfavourable. Conversely, if the chicken left its cage to feast so that something fell from its mouth and landed on the ground, these signs were termed
tripudium solistimum (or
tripudium quasi terripavium solistimum [from
solum, the ground], according to the ancient writers), ;ex caelo [
from the sky]: The observation and interpretation of thunder and lightning are the maximum auspicium sent by Jupiter. Whenever the natural phenomena of lightning and thunder are seen, it indicates that the
comitia, an assembly summoned by a magistrate cannot be held. The nature of the omen was decided based on what direction lightning came from. Signs from the left were considered lucky, while signs from the right were unlucky. ;ex quadrupedibus [from a four-footed animal] This type of divination is not used in auspices done officially for the state. It is usually practiced in private spaces. The appearance of any quadruped, including dogs, wolves, and horses, in 'a person's path, or in an unusual place', is taken as an augury. Additionally, Ex diris could be used to postpone comitia meetings if a participant suffered from
morbus comitialis, an epileptic fit.
Signs offered, requested or unsought There were two classifications of auspices;
impetrative (
impetrativa, sought or requested) and
oblative (
oblativa, unsought or offered).
Impetrativa were signs given in response to the augur's interpretation of the auspice.
Oblativa were unexpected and unsought events which occurred either while the magistrate was either taking auspices, or while he debated their likely significance. ==See also==
