Their minds being fully bent upon building, there arose presently a difference about the place where. Romulus chose what was called Roma Quadrata, or the Square Rome, and would have the city there. Remus laid out a piece of ground on the Aventine Mount, well fortified by nature, which was from him called Remonium, but now Rignarium. Concluding at last to decide the contest by a divination from a flight of birds, and placing themselves apart at some distance, Remus, they say, saw six vultures, and Romulus double the number; others say Remus did truly see his number, and that Romulus feigned his, but, when Remus came to him, that then he did, indeed, see twelve. Hence it is that the Romans, in their divinations from birds, chiefly regard the vulture, though Herodorus Ponticus relates that Hercules was always very joyful when a vulture appeared to him upon any action. For it is a creature the least hurtful of any, pernicious neither to corn, fruit-tree, nor cattle; it preys only upon carrion, and never kills or hurts any living thing; and as for birds, it touches not them, though they are dead, as being of its own species, whereas eagles, owls, and hawks mangle and kill their own fellow-creatures; yet, as Aeschylus says,-- What bird is clean that preys on fellow bird ? Besides all other birds are, so to say, never out of our eyes; they let themselves be seen of us continually; but a vulture is a very rare sight, and you can seldom meet with a man that has seen their young; their rarity and infrequency has raised a strange opinion in some, that they come to us from some other world; as soothsayers ascribe a divine origination to all things not produced either of nature or of themselves. When Remus knew the cheat, he was much displeased; and as Romulus was casting up a ditch, where he designed the foundation of the citywall, he turned some pieces of the work to ridicule, and obstructed others: at last, as he was in contempt leaping over it, some say Romulus himself struck him, others Celer, one of his companions; he fell, however, and in the scuffle Faustulus also was slain, and Plistinus, who, being Faustulus's brother, story tells us, helped to bring up Romulus. Celer upon this fled instantly into Tuscany, and from him the Romans call all men that are swift of foot Celeres; and because Quintus Metellus, at his father's funeral, in a few days' time gave the people a show of gladiators, admiring his expedition in getting it ready, they gave him the name of Celer.
