The origins of the different elements in Rome's foundation myth are a subject of ongoing debate. They may have come from the Romans' own
Italic origins, or from
Hellenic influences that were included later. Definitively identifying those original elements has so far eluded
classicists. Roman historians dated the founding of Rome around 753 BC, but the earliest known written account of the myth is from the late 3rd century BC. There is an ongoing debate about how and when the "complete" fable came together. Some elements are attested earlier than others, and the storyline and the tone were variously influenced by the circumstances and tastes of the different sources as well as by contemporary Roman politics and concepts of propriety. Whether the twins' myth was an original part of Roman myth or a later development is the subject of an ongoing debate.
Quintus Fabius Pictor's work became authoritative to the early books of Livy's
History of Rome,
Dionysius of Halicarnassus's
Roman Antiquities, and
Plutarch's
Life of Romulus. These three works have been among the most widely read versions of the myth. In all three works, the tales of the lupercal and the fratricide are overshadowed by that of the twins' lineage and connections to Aeneas and the deposing of Amulius. The latter receives the most attention in the accounts. Plutarch dedicates nearly half of his account to the overthrow of their uncle.
Roman Antiquities (Dionysius) Dionysius cites, among others, the histories of
Pictor,
Lucius Calpurnius Piso,
Cato the Elder,
Lucius Cincius Alimentus. The first book of Dionysius's twenty-volume history of Rome does not mention Remus until chapter 71. After spending another 8 chapters discussing the background of their birth in Alba, he dedicates a total of 9 chapters to the tale (79–87). Most of that is spent discussing the conflict with Amulius. He goes on to discuss the various accounts of the city's founding by others, and the lineage and parentage of the twins for another 8 chapters until arriving at the tale of their abandonment by the Tiber River. He spends the better part of the chapter 79 discussing the survival in the wild. Then the end of chapters 79 through 84 focuses on the account of their struggle with Amulius. Chapter 84 is an alternate, non-fantastical account of their survival; the augury and fratricide are discussed in chapters 85 to 88.
Ab Urbe Condita (Livy) Livy discusses the myth in chapters 4, 5, and 6 of his work's first book. p. 7 parentage 4 p. 8 survival. p. 8 the youth. 5 9–10 the struggle with Amulius. 6 p. 11 (the beginning only) the augury and fratricide.
Life of Romulus (Plutarch) Plutarch relates the legend in chapters 2–10 of
the Life of Romulus. He dedicates the most attention, nearly half the entire account, to conflict with Amulius.
Fasti (Ovid) Fasti, the epic Latin poem by
Ovid from the early 1st century AD, contains a complete account of the twins' tale. Notably, it relates a tale wherein the ghost of Remus appears to Faustulus and his wife, whom the poet calls "Acca". In the story, Remus appears to them while in bed and expresses his anger at Romulus's worker Celer for killing him on his own and affirms Romulus's fraternal love.
Roman History (Dio) Roman History by
Cassius Dio survives in fragments from various commentaries. They contain a more-or-less complete account. In them, he mentions an oracle that had predicted Amulius's death by a son of Numitor as the reason the Alban king expelled the boys. There is also a mention of "another Romulus and Remus" and another Rome having been founded long before on the same site.
Origo Gentis Romanae (unknown) This work contains a variety of versions of the story. In one, there is a reference to a
woodpecker bringing the boys food during the time they were abandoned in the wild. In one account of the conflict with Amulius, the capture of Remus is not mentioned. Instead, Romulus, upon being told of his true identity and the crimes suffered by him and his family at the hands of the Alban king, simply decided to avenge them. He took his supporters directly to the city and killed Amulius, afterwards restoring his grandfather to the throne.
