The twins Romulus and Remus were borne by Ilia, daughter of king Numitor, and the war-god Mars. They were condemned by King Amulius, the ruler of Alba, to be cast into the river. The king’s servants took the children and carried them from Alba as far as the Tiber on the Palatine Hill. However, when they tried to descend the hill to the river to carry out the command, they found that the river had risen and they were unable to reach its bed. They therefore thrust the tub which the children slept into the shallow water at the shore.
The tub floated for a while before the water promptly receded. The tub then knocked against a stone and the screaming infants were thrown into the river mud. They were heard by a she-wolf. She came and gave her teats to the boys to nurse them and, as they were drinking, she licked them clean with her tongue. A woodpecker flew above them to guard the children and bring them food. These were Mars’ doing as the wolf and the woodpecker are animals consecrated to him
These odd happenings were seen by one of the royal herdsmen who was driving his pigs back to the pasture. Startled, he summoned his friends. They all made a loud noise to scare the wolf away, but the wolf was not afraid. Calmly ignoring the herdsmen, she disappeared into the wilderness of the forest. Meanwhile the men picked up the boys and carried them to the chief swineherd of the king, Faustulus, as they believed that the gods did not wish the children to die. But Faustulus’ wife had just given birth to a dead child and was full of sorrow. Faustulus gave her the twins to nurse and the couple raised the children. They named them them Romulus and Remus.
Evidently, the twin never forgotten the wolf. After Rome had been founded, king Romulus built himself a house not far from the place where his tub had stood. The gully in which the she-wolf had disappeared was renamed as the Lupercal (the Wolf’s Gully). The image of the she-wolf with the twins was subsequently erected at this spot and the she-wolf herself, the Lupa, was worshipped by the Romans as a divinity.
This saga later on underwent manifold transmutations, mutilations, additions, and interpretations. It is best known in the form transmitted by Livy, where we learn something about the fate of the twins:
King Proca bequeaths the royal dignity to his firstborn son, Numitor. But his younger brother, Amulius, pushes him from the throne, and becomes king himself. So that no scion from Numitor’s family may arise, as the avenger, he kills the male descendants of his brother. Rhea Silvia, the daughter, he elects as a vestal, and thus deprives her of the hope of progeny, through perpetual virginity as enjoined upon her under the semblance of a most honorable distinction. But the vestal maiden was overcome by violence, and having brought forth twins, she named Mars as the father of her illegitimate offspring, be it from conviction, or because a god appeared more creditable to her as the perpetrator of the crime. The narrative of the exposure in the Tiber goes on to relate that the floating tub, in which the boys had been exposed, was left on dry land by the receding waters, and that a thirsty wolf, attracted from the neighboring mountains by the children’s cries, offered them her teats. The boys are said to have been found by the chief royal herder, supposedly named Faustulus, who took them to the homestead of his wife, Larentia, where they were raised. Some believe that Larentia was called Lupa (“she-wolf”) by the herders because she offered her body, and that this was the origin of the wonderful saga.
Grown to manhood, the youths Romulus and Remus protect the herds against the attacks of wild animals and robbers. One day Remus is taken prisoner by the robbers, who accuse him of having stolen Numitor’s flocks. But Numitor, to whom he is surrendered for punishment, was touched by his tender age, and when he learned of the twin brothers, he suspected that they might be his exposed grandsons. While he was anxiously pondering the resemblance with the features of his daughter, and the boy’s age as corresponding to the time of the exposure, Faustulus arrived with Romulus, and a conspiracy was hatched when the descent of the boys had been learned from the herders. The youths armed themselves for vengeance, while Numitor took up weapons to defend his claim to the throne he had usurped. After Amulius had been assassinated, Numitor was reinstituted as the ruler, and the youths resolved to found a city in the region where they had been exposed and brought up. A furious dispute arose upon the question of which brother was to be the ruler of the newly erected city, for neither twin was favored by the right of primogeniture, and the outcome of the bird oracle was equally doubtful. The saga relates that Remus jumped over the new wall, to deride his twin, and Romulus became so much enraged that he slew his brother. Romulus then usurped the sole mastery, and the city was named Rome after him.
