National myth in the context of "Mythological"

Myth is a genre of folklore consisting primarily of narratives that play a fundamental role in a society. For scholars, this is totally different from the ordinary sense of the term myth, meaning a belief that is not true, as the veracity of a piece of folklore is entirely irrelevant to determining whether it constitutes a myth.

Myths are often endorsed by religious and secular authorities, and may be natural or supernatural in character. Many societies group their myths, legends, and history together, considering myths and legends to be factual accounts of their remote past. In particular, creation myths take place in a primordial age when the world had not achieved its later form. Origin myths explain how a society's customs, institutions, and taboos were established and sanctified. National myths are narratives about a nation's past that symbolize the nation's values. There is a complex relationship between recital of myths and the enactment of rituals.

Etiology (/ˌiːtiˈɒlədʒi/; alternatively spelled aetiology or ætiology) is the study of causation or origination. The word is derived from the Greek word αἰτιολογία (aitiología), meaning "giving a reason for" (from αἰτία (aitía) 'cause' and -λογία (-logía) 'study of'). More completely, etiology is the study of the causes, origins, or reasons behind the way that things are, or the way they function, or it can refer to the causes themselves. The word is commonly used in medicine (pertaining to causes of disease or illness) and in philosophy, but also in physics, biology, psychology, political science, geography, cosmology, spatial analysis and theology in reference to the causes or origins of various phenomena.

In the past, when many physical phenomena were not well understood or when histories were not recorded, myths often arose to provide etiologies. Thus, an etiological myth, or origin myth, is a myth that has arisen, been told over time or written to explain the origins of various social or natural phenomena. For example, Virgil's Aeneid is a national myth written to explain and glorify the origins of the Roman Empire. In theology, many religions have creation myths explaining the origins of the world or its relationship to believers.
