But of more historical importance is the difference of opinion between the two brothers respecting the building of the city and its site.  According to the ancient tradition, both were kings and the equal heads of the colony; Romulus is universally said to have wished to build on the Palatine, while Remus, according to some, preferred the Aventine; according to others, the hill Remuria.  Plutarch states that the latter is a hill three miles south of Rome, and cannot have been any other than the hill nearly opposite St. Paul, which is the more credible, since this hill, though situated in an otherwise unhealthy district, has an extremely fine air:  a very important point in investigations respecting the ancient Latin towns, for it may be taken for certain that where the air is now healthy it was so in those times also, and that where it is now decidedly unhealthy, it was anciently no better.  The legend now goes on to say that a dispute arose between Romulus and Remus as to which of them should give the name to the town, and also as to where it was to be built.  A town Remuria therefore undoubtedly existed on that hill, though subsequently we find the name transferred to the Aventine, as is the case so frequently.  According to the common tradition, the auguries were to decide between the brothers:  Romulus took his stand on the Palatine, Remus on the Aventine.  The latter observed the whole night, but saw nothing until about sunrise, when he saw six vultures flying from north to south, and sent word of it to Romulus; but at that very time the latter, annoyed at not having seen any sign, fraudulently sent a messenger to say that he had seen twelve vultures, and at the very moment the messenger arrived there did appear twelve vultures, to which Romulus appealed.  This account is impossible; for the Palatine and Aventine are so near each other that, as every Roman well knew, whatever a person on one of the two hills saw high in the air, could not escape the observation of any one who was watching on the other.  This part of the story therefore cannot be ancient, and can be saved only by substituting the Remuria for the Aventine.  As the Palatine was the seat of the noblest patrician tribe, and the Aventine the special town of the plebeians, there existed between the two a perpetual feud, and thus it came to pass that in after times the story relating to the Remuria, which was far away from the city, was transferred to the Aventine.  According to Ennius, Romulus made his observations on the Aventine; in this case Remus must certainly have been on the Remuria, and it is said that when Romulus obtained the augury he threw his spear toward the Palatine.  This is the ancient legend which was neglected by the later writers.  Romulus took possession of the Palatine.  The spear taking root and becoming a tree, which existed down to the time of Nero, is a symbol of the eternity of the new city, and of the protection of the gods.  The statement that Romulus tried to deceive his brother is a later addition; and the beautiful poem of Ennius, quoted by Cicero, knows nothing of this circumstance.  The conclusion which must be drawn from all this is, that in the earliest times there were two towns, Roma and Remuria, the latter being far distant from the city and from the Palatine.
