20190710_143740 A sculpture of Perkūnas in the Samogitian sanctuary
Samogitian Alka, or Samogitian sanctuary ("Žemaičių Alka") is a little pagan sanctuary in Lithuania, on the coast of the Baltic sea, north of the Šventoji town. It's situated on the small hill by the beach. The wooden plankway goes over the dunes to the beach. You can see the sea from here, which, I suppose, makes it a perfect place for pagan rituals.
It consists of about a dozen wooden poles, which are statues of various ancient Baltic gods, carved by Lithuanian folk artists in the late 20th century.
This is a sculpture of Perkūnas, an ancient Baltic pagan sky god in the Samogitian sanctuary / Žemaičių alka. It's not so much the likeness of the god as a symbolic representation of him. Why this particular shape was chosen for Perkūnas, I don't know. Just like I don't know why other shapes were chosen for other gods of the Baltic patheon (if you can call it that, considering that written knowledge about ancient polytheistic Baltic religions is extremely scarce, and any mentions of Baltic deities in the Middle Ages were made by Christian monks, scribes and politicians -- people who didn't hold polytheistic religions in high regard).
