The unsavoury elements of many of the myths concerning Romulus have led some scholars to describe them as "shameful" or "disreputable." In antiquity such stories became part of anti-Roman and anti-pagan propaganda. More recently, the historian Hermann Strasburger postulated that these were never part of authentic Roman tradition, but were invented and popularized by Rome's enemies, probably in Magna Graecia, during the latter part of the fourth century BC. This hypothesis is rejected by other scholars, such as Tim Cornell (1995), who notes that by this period, the story of Romulus and Remus had already assumed its standard form, and was widely accepted at Rome. Other elements of the Romulus mythos clearly resemble common elements of folk tale and legend, and thus strong evidence that the stories were both old and indigenous. Likewise, Momigliano finds Strasburger's argument well-developed, but entirely implausible; if the Romulus myths were an exercise in mockery, they were a signal failure.
