MORANA (Maržanna, Mara, Maržena, Morana, Moréna, Mora, Marmora or Morena, and also Marzaniok) was a Slavic goddess of winter and death. Morana was a goddess of a long and cold winter, a winter that could bring death through famine and extreme cold, and which could cause disease and massive death of the cattle.
Morana’s name most likely comes from the Proto-Indo-European root *mar-, *mor-, signifying death. Some theories claim her name is derived from the same Indo-European root as the Latin mors, ‘death,’ and Russian mor, ‘pestilence’. Some authors also likened her to a mare, an evil spirit in Germanic and Slavic folklore, associated with nightmares and sleep paralysis. That spirit is named Mora, which could be just one form of Morana. In Belarus, Polish, Ukrainian and in some Russian dialects, the word mara means ‘phantom’, ‘vision’ or ‘hallucination’.
