The Romans knew that they had once been ruled by kings, and they believed, perhaps rightly, that the fall of the monarchy had taken place at what we would call the end of the sixth century B.C. The texts that tell us this – Livy, Dionysius, Plutarch, etc. – all depend on a historical tradition that can be traced back as far as the second half of the third century B.C., when the Roman literary genres of historical drama, historical epic, and prose historiography began. Before that, we do not know how the Romans conceived or recorded the memory of their own past.
