Devana or Dziewanna is the Slavic equivalent of the Roman goddess Diana , mentioned by 15th century
Polish historian Jan Długosz in Annales seu cronici incliti regni Poloniae (History of Poland). Her name, though similar to Diana's, is apparently derived from Slavic word that means 'virgin' or 'maiden' (deva, dziewica). However, most of contemporary scholars don't regard Annales seu cronici incliti regni Poloniae as a reliable source on Slavic mythology and have doubts about existence of such deity in Slavic pantheon.
