Old Bohemian legends accompany each Czech from chidhood. Tales, myths and legends are not backed by historical evidence, but they survived to the present day in folk stories and legends recorded by chroniclers Kosmas, Dalimil and Václav Hájek of Libočany, as well as in Ancient Bohemian Legends written by renowned Czech 19^th century writer Alois Jirásek. They tell stories about the oldest period of the Czech history – approximately between 6^th and 10^th century, up to the period of duke Bořivoj, the first documented Přemyslid ruler.
