In Slavic mythology, Perperuna or Dodola was the (wife) of the god Perun, the god of thunder. In south-eastern Europe, there are still rain-making ceremonies featuring a young girl called Perperuna or Dodola.
Dodola (also spelled Dudulya and Didilya, pronounced: doh-doh-la, doo-doo-lya, or dee-dee-lya) or Perperuna is a being in old Slavic mythology.
According to some interpretations, she is the Slavic goddess of rain, and the wife of the supreme god Perun (who is the god of thunder).
Bulgarian and Serbian Slavs used to organise the Dodo-le (or Perperuna) festival in times of drought, where they worshipped the goddess and prayed to her for rain.
