Ancient Romans predicted the end of the world twice. Both prophecies were related to a preached myth in which 12 eagles were revealed to Romulus.
The first interpretation was that each eagle represented a period of 10 years. Therefore, the destruction of the world was assumed in 634 BCE (120 AUC – ab urbe condita) as Rome was founded in 753 BCE (in the Roman system of counting, the so-called 1 AUC).
The second – was in 389 BCE (365 AUC) because 12 birds represented the number of months of the year, according to her proponents.
