Augury is the practice from ancient Roman religion of interpreting omens from the observed flight of birds. When the individual, known as the augur, interpreted these signs, it is referred to as "taking the auspices". 'Augur' and 'auspices' are from the Latin auspicium and auspex, literally "one who looks at birds". Depending upon the birds, the auspices from the gods could be favorable or unfavorable (auspicious or inauspicious). Sometimes bribed or politically motivated augurs would fabricate unfavorable auspices in order to delay certain state functions, such as elections.[citation needed] Pliny the Younger attributes the invention of auspicy to Tiresias the seer of Thebes, the generic model of a seer in the Greco-Roman literary culture.
