Meaning & History
Křesomysl's name is thought to be derived from the old Slavonic words "křesat" meaning to strike a light and "mysl" meaning mind or spirit thus literally the name should have meant "lighting the mind". The suffix -mysl is also in the other mythical names Přemysl and Nezamysl. Záviš Kalandra thought the names of the seven princes were cryptic names of ancient Slavonic days of the week - Křesomysl being the fifth - Thursday, in Latin Iovis Dies whereas Jupiter and Thor were both gods of thunder the word "křesat" is explained here as to strike the lightnings. Another theory says that the names were mistaken from a coherent and partly interrupted old Slavonic text.
