Medeina or Medeinė (from Lithuanian: medis – "tree" or medė – "forest"),[1] often treated as synonymous to Žvorūnė or Žvorūna (derived from žvėris – "beast"), is one of the main deities in the Lithuanian mythology, and is similar to Latvian Meža māte (Forest Mother).
[1] A Slavic transcription of John Malalas' Chronicle (dated 1261) mentioned Žvorūna and three other gods.
The Hypatian Codex, describing events of 1252, mentioned pagan gods still worshiped by King Mindaugas.
[2] According to research by Algirdas Julius Greimas, Medeina is single, unwilling to get married, though voluptuous and beautiful huntress.
[5] Vykintas Vaitkevičius identified five Hare Churches (sacred stones, hills, forests) and ten Wolf-footprints (stones with hollows that resemble a footprint) in Eastern Lithuania (former Duchy of Lithuania) that were related to the cult of Medeina.
