omina

An omen is an observed phenomenon interpreted as a sign of future good or bad fortune. In ancient times, omens were diverse, including natural events like lightning, cloud movements, and the behavior of birds and animals. The interpretation of these signs was a specialized practice, particularly in ancient Rome, where augurs observed phenomena to determine if the gods approved of proposed actions, especially in political and military matters.123

These signs could be deliberately sought, such as thunder or the behavior of sacred chickens, or they could occur incidentally, like the unexpected appearance of certain animals. The practice of interpreting omens, or augury, was widespread and ancient, with similar traditions found in various cultures. These interpretations were considered crucial for significant undertakings, from elections to military campaigns.23
