What god did the Oeselians worship?
The superior god of Oeselians as described by Henry of Latvia was called Tharapita. According to the legend in the chronicle Tharapita was born on a forested mountain in Virumaa (Latin: Vironia), mainland Estonia from where he flew to Oesel, Saaremaa The name Taarapita has been interpreted as "Taara, help!"/"Thor, help!" (Taara a(v)ita in Estonian) or "Taara keeper"/"Thor keeper" (Taara pidaja) Taara is associated with the Scandinavian god Thor. The story of Tharapita's or Taara's flight from Vironia to Saaremaa has been associated with a major meteor disaster estimated to have happened in 660 ± 85 BC that formed Kaali crater in Saaremaa.
