[expand]Christianity could not eliminate Kupolės—the festival was too deeply embedded in agricultural calendar, too essential for community bonding, too spectacular in execution to suppress completely. Instead, the Church adapted it, transforming summer solstice celebration into St. John’s Eve (Joninės in Lithuanian), attributing the bonfires to Christian saint rather than solar goddess Saule.
The adaptation was superficial overlay rather than fundamental transformation. The fires still burned on hilltops at solstice. The young people still jumped flames and wore flower wreaths. The herbs were still gathered during shortest night. The burning wheels still rolled downhill. The basic ritual structure remained unchanged despite new theological justification claiming Christian rather than pre-Christian origin.
Folk practice maintained deeper continuity. The songs sung at Kupolės, while occasionally including Christian verses added to satisfy priestly observation, preserved pre-Christian content celebrating sun, summer, fertility without reference to saints or biblical narratives. The divination practices—wreath burning, fern flower searching, river floating—continued without Christian equivalent, being tolerated as “harmless folklore” while maintaining pre-Christian spiritual understanding.
The festival survived because its core functions remained necessary regardless of official theology. Communities still needed summer gathering reinforcing social bonds. Young people still required structured opportunities for romantic pairing. Agricultural calendar still demanded acknowledgment of solstice transition. Medicinal herb gathering still depended on seasonal timing. The theological framework could shift from Saule worship to St. John veneration, but the underlying practical reality remained unchanged, ensuring ritual continuity through doctrinal transformation.
