This article deals with Slavic pseudo-mythology, comprising myths and deities that do not exist in authentic mythology and folklore or whose existence is doubtful or refuted. It is typically an artificial construct and may be created by scholars who freely interpret scarce sources. This pseudo-mythology, as we will see, has created a false reality. The image we have of Slavic paganism is in fact very vague for lack of sources. On the contrary, today we are used to talking about a (...) well-constructed mythology which in fact rests on the construction based on assumptions and pseudo-theories of the 18th, mainly of the 19th and 20th centuries. This phenomenon is also related to Rodnovery or Rodnovery, which is a Slavic neo-pagan reconstructionist movement. (shrink)
