Marzanna (in Polish), Morė (in Lithuanian) or Morena (in Czech, Slovak, Russian) or also Mara, Maržena, Morana, Moréna, Mora or Marmora is a Baltic and Slavic goddess associated with seasonal agrarian rites based on the idea of death and rebirth of nature. She is associated with death and winter and is often described as the goddess of death. As the Goddess of death and winter she appears in different guises. Her proficiency in different guises is a reoccurring trait that sticks out in the stories told about her. To this day in some regions of Poland, there is a festival held where an effigy of Marzanna is made in the month of March, and is burned to symbolize the triumph of springtime over winter. This is known as The Burning and Drowning Ritual of Marzanna.

  • Some medieval Christian sources such as the Czech 9th century Mater Verborum also compare her to the Greek goddess Hecate , associating her with sorcery. 15th century Polish chronicler Jan Długosz likened her to Ceres , the Roman goddess of agriculture.
