Foundation legends

The specific date, circumstances, and motivations concerning Carthage's founding are unknown. All surviving accounts of the city's origins come from Latin and Greek literature, which are generally legendary in nature but may have some basis in fact.

The standard foundation myth across all sources is that the city was founded by colonists from the ancient Phoenician city-state of Tyre, led by its exiled princess Dido (also known as Queen Elissa or Alissar). Dido's brother, Pygmalion (Phoenician: Pummayaton) had murdered her husband, the high priest of the city, and taken power as a tyrant. Dido and her allies escaped his reign and established Carthage, which became a prosperous city under her rule as queen. Several scholars have identified Baa‘li-maanzer, the king of Tyre who gave tribute to Shalmaneser III in 841 BC, with 𐤁𐤏𐤋𐤏𐤑𐤅𐤓 Ba‘al-'azor (Phoenician form of the name) or Baal-Eser/Balazeros (Greek form of the name), Dido's grandfather. The Nora Stone, found on Sardinia, has been interpreted by Frank Moore Cross as naming Pygmalion as the king of the general who was using the stone to record his victory over the local populace. On paleographic grounds, the stone is dated to the 9th century BC. (Cross's translation, with a longer discussion of the Nora stone, is found in the Pygmalion article). If Cross's interpretation is correct, this presents inscriptional evidence substantiating the existence of a 9th-century-BC king of Tyre named (in Greek) Pygmalion.

The Roman historian Justin, writing in the second century AD, provides an account of the city's founding based on the earlier work of Trogus. Princess Dido is the daughter of King Belus II of Tyre, who upon his death bequeaths the throne jointly to her and her brother Pygmalion. After cheating his sister out of her share of political power, Pygmalion murders her husband Acerbas (Phoenician: Zakarbaal), also known as Sychaeus, the High Priest of Melqart, whose wealth and power he covets. Before her tyrannical brother can take her late husband's wealth, Dido immediately flees with her followers to establish a new city abroad.

Upon landing in North Africa, she is greeted by the local Berber chieftain, Iarbas (also called Hiarbas) who promises to cede as much land as could be covered by a single ox hide. With her characteristic cleverness, Dido cuts the hide into very thin strips and lays them end to end until they encircle the entire hill of Byrsa. While digging to set the foundation of their new settlement, the Tyrians discover the head of an ox, an omen that the city would be wealthy "but laborious and always enslaved". In response they move the site of the city elsewhere, where the head of a horse is found, which in Phoenician culture is a symbol of courage and conquest. The horse foretells where Dido's new city will rise, becoming the emblem of Carthage, derived from the Phoenician Qart-Hadasht, meaning "New City".

The city's wealth and prosperity attracts both Phoenicians from nearby Utica and the indigenous Libyans, whose king Iarbas now seeks Dido's hand in marriage. Threatened with war should she refuse, and also loyal to the memory of her deceased husband, the queen orders a funeral pyre to be built, where she commits suicide by stabbing herself with a sword. She is thereafter worshiped as a goddess by the people of Carthage, who are described as brave in battle but prone to the "cruel religious ceremony" of human sacrifice, even of children, whenever they seek divine relief from troubles of any kind.

Virgil's epic poem the Aeneid —written over a century after the Third Punic War—tells the mythical story of the Trojan hero Aeneas and his journey towards founding Rome, inextricably tying together the founding myths, and ultimate fates, of both Rome and Carthage. Its introduction begins by mentioning "an ancient city" that many readers likely assumed was Rome or Troy, but goes on to describe it as a place "held by colonists from Tyre, opposite Italy... a city of great wealth and ruthless in the pursuit of war. Its name was Carthage, and Juno is said to have loved it more than any other place... But she had heard that there was rising from the blood of Troy a race of men who in days to come would overthrow this Tyrian citadel... sack the land of Libya."

Virgil describes Queen Elissa—for whom he uses the ancient Greek name, Dido, meaning "beloved"—as an esteemed, clever, but ultimately tragic character. As in other legends, the impetus for her escape is her tyrannical brother Pygmalion, whose secret murder of her husband is revealed to her in a dream. Cleverly exploiting her brother's greed, Dido tricks Pygmalion into supporting her journey to find and bring back riches for him. Through this ruse she sets sail with gold and allies secretly in search of a new home.

As in Justin's account, upon landing in North Africa, Dido is greeted by Iarbas, and after he offers as much land as could be covered by a single ox hide, she cuts the hide into very thin strips and encircles all of Byrsa. While digging to set the foundation of their new settlement, the Tyrians discover the head of a horse, which in Phoenician culture is a symbol of courage and conquest. The horse foretells where Dido's new city will rise, becoming the emblem of the "New City" Carthage. In just seven years since their exodus from Tyre, the Carthaginians build a successful kingdom under Dido's rule. She is adored by her subjects and presented with a festival of praise. Virgil portrays her character as even more noble when she offers asylum to Aeneas and his men, who had recently escaped from Troy. The two fall in love during a hunting expedition, and Dido comes to believe they will marry. Jupiter sends a spirit in the form of the messenger god, Mercury, to remind Aeneas that his mission is not to stay in Carthage with his new-found love Dido, but to sail to Italy to found Rome. The Trojan departs, leaving Dido so heartbroken that she commits suicide by stabbing herself upon a funeral pyre with his sword. As she lies dying, she predicts eternal strife between Aeneas' people and her own, proclaiming "rise up from my bones, avenging spirit" in an invocation of Hannibal. Aeneas sees the smoke from the pyre as he sails away, and though he does not know the fate of Dido, he identifies it as a bad omen. Ultimately, his descendants go on to found the Roman Kingdom, the predecessor of the Roman Empire.

Like Justin, Virgil's story essentially conveys Rome's attitude towards Carthage, as exemplified by Cato the Elder 's famous utterance, " Carthago delenda est "—"Carthage must be destroyed". In essence, Rome and Carthage were fated for conflict: Aeneas chose Rome over Dido, eliciting her dying curse upon his Roman descendants, and thus providing a mythical, fatalistic backdrop for a century of bitter conflict between Rome and Carthage.

These stories typify the Roman attitude towards Carthage: a level of grudging respect and acknowledgement of their bravery, prosperity, and even their city's seniority to Rome, along with derision of their cruelty, deviousness, and decadence, as exemplified by their practice of human sacrifice.
