Augury
from Latin auspicium, meaning one who divines by looking at birds
A Roman rite of reading bird behavior to learn the will of the gods
Augury was a formal Roman religious practice where specialists watched birds to interpret divine signs. The method expanded over time to include thunder and animal entrails, serving as a crucial check on political power and public action.
- Romulus saw twelve vultures while Remus saw six during the founding of Rome
- Augurs used a lituus wand to mark sacred spaces in the sky
- Chickens were starved before being fed to ensure eager eating for good omens
- Only patricians could be augurs until a law changed the rule in 300 BCE
- Lightning from the left was considered lucky while right-side strikes were unlucky
What it is
Augury served as a primary method for Romans to discern the intentions of their deities through natural signs. The core practice involved watching the flight and songs of birds to determine if an action was permitted. Specialists known as augurs interpreted these events, a process called taking the auspices. Over centuries, the scope of this divination widened. It eventually incorporated the study of lightning and thunder, as well as the examination of animal organs. This system provided a religious framework for political decisions and military campaigns.
Where it comes from
Ancient sources claim that observing bird signs predates the city of Rome itself. The practice appears in earlier cultures, including the Etruscans and Greeks. In Cyprus, records from Egypt mention an eagle diviner being requested by local kings. Greek tradition featured seers like Calchas who read bird movements. The Romans adopted and refined these older methods, creating strict rules for interpretation. Stoic philosophers later argued that such signs proved the gods cared for human affairs.
How it is done
An augur would stand in a marked area facing south to define a sacred space in the sky. He then observed specific birds or weather patterns. Birds were divided into groups based on how they gave signs. Some were judged by their songs, while others were judged by their flight paths. Another method involved feeding chickens and watching their eating habits. If the birds ate eagerly, it signaled approval. Refusal to eat indicated disapproval. Lightning direction also determined the outcome, with left-side strikes viewed as lucky.
Tools and materials
The augur wore specific robes depending on the setting. A special wand called a lituus was used to mark the sacred boundaries in the air. A clay vessel known as a capis held offerings for sacrifices. These items appeared frequently on coins issued by the officials. The physical setup required a clear view of the sky and a designated ground area bounded by stationary objects.

What it is for
This practice was essential for validating public actions. No magistrate could begin a campaign, pass a law, or hold an election without favorable signs. The results dictated whether the state should proceed or wait. Politicians sometimes manipulated these readings to delay opponents. The system ensured that major decisions aligned with perceived divine will rather than mere human desire.
Who does it
Only patricians could serve as augurs until three hundred years before the common era. This monopoly kept lower classes from influencing religious judgments. A new law later opened the position to plebeians, increasing the number of officials. These readers kept detailed books of past signs and rituals. Magistrates themselves often had to understand basic interpretations to perform their duties correctly.
Peoples and places
The Romans formalized augury into a state institution. They borrowed elements from neighboring Etruscan traditions, such as reading thunder. Greek culture previously relied more on liver inspection than bird watching. The Phoenicians and Chaldeans also practiced similar forms of divination. Roman historians noted differences between their own systems and those of other nations.

What people believe
Romans believed that Jupiter communicated through birds and weather. Errors in interpreting signs were seen as offensive to the gods. Such mistakes could bring disaster unless corrected. The system operated on the premise that the divine realm actively guided human choices. Silence and proper ritual were required to receive clear messages.
When it is done
Auspices were taken whenever public business arose. Elections, legal proceedings, and military movements all required prior consultation. The validity of a sign often lasted only for the day or the duration of the specific event. Military camps had dedicated areas for these readings.
How scholars and sceptics see it
Historians note that augury evolved from simple observation to complex regulation. Cicero documented the shift toward studying animal entrails instead of just birds. Modern scholars recognize the political utility of the practice. Patricians used religious authority to block popular demands. The opening of the role to plebeians changed the balance of power.
Cautions and what is closed
Misinterpreting signs was considered dangerous. It risked angering the gods and causing harm to the community. Political actors sometimes fabricated bad omens to stop rivals. This manipulation undermined the integrity of the religious system.
Compare and confuse
Augury differs from haruspicy, which focuses on internal organs. It also contrasts with Greek oracle traditions that relied on prophetic speech. Other cultures used similar bird watching but lacked the strict Roman legal framework.
Law and persecution
The practice was deeply embedded in Roman law. Public acts were invalid without positive auspices. The Lex Ogulnia changed who could interpret the signs. This legal shift allowed common citizens to challenge elite religious decisions.
