The phrase 'Sacra Canunt' translates to 'they sing sacred things' and is often used to indicate the performance of religious rites or rituals, particularly in the context of invoking divine favor. In the Aeneid, this phrase emphasizes the role of divine intervention and the importance of piety in the narrative, particularly during moments of worship or supplication. It connects deeply to themes of fate, divine will, and the responsibilities of characters in relation to the gods.
