Founding myth

A founding myth or etiological myth (Greek aition) explains either:

Beginning in prehistorical times, many civilizations and kingdoms adopted some version of a heroic model national origin myth, including the Hittites and Zhou dynasty in the Bronze Age; the Scythians, Wusun, Romans and Goguryeo in Antiquity; Turks and Mongols during the Middle Ages; and the Dzungar Khanate in the late Renaissance.

In the founding myth of the Zhou dynasty in China, Lady Yuan makes a ritual sacrifice to conceive, then becomes pregnant after stepping into the footprint of the King of Heaven. She gives birth to a son, Hou Ji, whom she leaves alone in dangerous places where he is protected by sheep, cattle, birds, and woodcutters. Convinced that he is a supernatural being, she takes him back and raises him. When he grows to adulthood, he takes the position of Master of Horses in the court of Emperor Yao, and becomes successful at growing grains, gourds and beans. According to the legend, he becomes founder of the Zhou dynasty after overthrowing the evil ruler of Shang.

Like other civilizations, the Scythians also claimed descent from the son of the god of heaven. One day, the daughter of the god of the Dnieper River stole a young man's horses while he was herding his cattle, and forced him to lie with her before returning them. From this union, she conceived three sons, giving them their father's greatbow when they came of age. The son who could draw the bow would become king. All tried, but only the youngest was successful. On his attempt, three golden objects fell from the sky: a plow and yoke, a sword, and a cup. When the eldest two tried to pick them up, fire prevented them. After this, it was decided the youngest son, Scythes, would become king, and his people would be known as Scythians.

The Torah (or Pentateuch, as biblical scholars sometimes call it) is the collective name for the first five books of the Bible: Genesis, Exodus, Leviticus, Numbers, and Deuteronomy. It forms the charter myth of Israel, the story of the people's origins and the foundations of their culture and institutions, and it is a fundamental principle of Judaism that the relationship between God and his chosen people was set out on Mount Sinai through the Torah, though many stories are adapted from older religions.

A founding myth may serve as the primary exemplum, as the myth of Ixion was the original Greek example of a murderer rendered unclean by his crime, who needed cleansing (catharsis) of his impurity.

Founding myths feature prominently in Greek mythology. "Ancient Greek rituals were bound to prominent local groups and hence to specific localities", Walter Burkert has observed, "i.e., the sanctuaries and altars that had been set up for all time". Thus Greek and Hebrew founding myths established the special relationship between a deity and local people, who traced their origins from a hero and authenticated their ancestral rights through the founding myth. Greek founding myths often embody a justification for the ancient overturning of an older, archaic order, reformulating a historical event anchored in the social and natural world to valorize current community practices, creating symbolic narratives of "collective importance" enriched with metaphor to account for traditional chronologies, and constructing an etiology considered to be plausible among those with a cultural investment.

In the Greek view, the mythic past had deep roots in historic time, its legends treated as facts, as Carlo Brillante has noted, its heroic protagonists seen as links between the "age of origins" and the mortal, everyday world that succeeded it. A modern translator of Apollonius of Rhodes ' Argonautica has noted, of the many aitia embedded as digressions in that Hellenistic epic, that "crucial to social stability had to be the function of myths in providing explanations, authorization or empowerment for the present in terms of origins: this could apply, not only to foundations or charter myths and genealogical trees (thus supporting family or territorial claims) but also to personal moral choices." In the period after Alexander the Great expanded the Hellenistic world, Greek poetry— Callimachus wrote a whole work simply titled Aitia —is replete with founding myths. Simon Goldhill employs the metaphor of sedimentation in describing Apollonius' laying down of layers "where each object, cult, ritual, name, may be opened... into a narrative of origination, and where each narrative, each event, may lead to a cult, ritual, name, monument."

A notable example is the myth of the foundation of Rome—the tale of Romulus and Remus, which Virgil in turn broadens in his Aeneid with the odyssey of Aeneas and his razing of Lavinium, and his son Iulus 's later relocation and rule of the famous twins' birthplace Alba Longa, and their descent from his royal line, thus fitting perfectly into the already established canon of events. Similarly, the Old Testament's story of the Exodus serves as the founding myth for the community of Israel, telling how God delivered the Israelites from slavery and how they therefore belonged to him through the Covenant of Mount Sinai.

During the Middle Ages, founding myths of the medieval communes of northern Italy manifested the increasing self-confidence of the urban population and the will to find a Roman origin, however tenuous and legendary. In 13th-century Padua, when each commune looked for a Roman founder – and if one was not available, invented one—a legend had been current in the city, attributing its foundation to the Trojan Antenor.

Larger-than-life heroes continue to bolster the origin-myths of many newer nations and societies. In modern-era colonial contexts, waves of individuals and groups come to the fore in popular history as shaping and exemplifying the ideals of a group: explorers followed by conquerors followed by developers/exploiters. Note for example the conquistadors of the Iberian empires, the bandeirantes in Brazil, the coureurs des bois in Canada, the Cossacks and the promyshlenniki in Siberia and in Alaska, the bands of pioneers in the central and western United States, and the voortrekkers in Southern Africa.
