Record summary
Julius Obsequens’ Liber Prodigiorum preserves reports of unusual Roman portents, including luminous phenomena, strange objects, aerial appearances and other prodigies. Later UFO writers have mined translations for apparent ancient sightings, but the work is a late compilation dependent on Livy and other lost sources. Its categories belong to Roman religious and historiographical culture rather than modern aviation observation. The text is valuable for studying how unusual sky reports were transmitted, edited and interpreted, while the original contexts and wording of many entries remain uncertain.
