From the very beginning of the Middle Ages, the Czech Lands and the Přemyslids dynasty acquired a dualistic form of identity. A more original element is a ’pagan’ one and derives from the holy marriage of Přemysl the Ploughman and Libuše, the Purveyor of Justice, Prophetess and Princess. This duality has numerous analogies such as that the aim of the kings’ rule is ‘peace and a year of plenty’. Even though Přemysl is designated a ‘Ploughman‘, he only ploughs on a small area of land, where he ritually ensures a good harvest. Because (as his name in Czech suggests) he also ‘thought up‘ laws for the previously savage Czechs, he also personifies a figure fulfilling the so-called social function (according to Dumézil). A military function may be absent here but it is present in the tale of the war with the Lučané. As the hagiographer Kristián shows, Saint Wenceslas (died 935) personifies the Christian transformation of this tale and is the preserver of ‘the peace‘ in the sense of justice (as our intercessor before God).
