Záboj
Záboj and Slavoj are two invented national heroes of the Czech past, two minstrel-warriors. They are found in Václav Hanka's spurious medieval Manuscript of Dvůr Kralové, allegedly "discovered" in 1817 in the tower of a local church and not exposed as a literary hoax, by Jan Gebauer in Masaryk's journal Athenaeum, until 1886.
