One of the most unique gifts I have ever received came from a cousin who lives in a small village in Poland. He handed me a precious gift at our first meeting with these words of caution, “Now this candle is special. It should only be lit during lightning storms or if someone in your house is on their death bed.”
This lovely candle is a gromnica (plural gromnice) and is also known as a Thunder Candle. The Polish word “grom” means a clap of thunder. Almost every Catholic home in Poland will have at least one of these long and relatively thick candles that are decorated with religious symbols and images. In modern times, the gromnice is stored away carefully for important ceremonies such as a christening, First Communion, Confirmation or Anointing.
The most important function of gromnice has not been ceremonial but protective. As its name implies, the gromnica was believed to protect against thunderstorms and was lit and placed in windows to keep lightning away. My ancestors’ village was in the middle of a huge forest, and I can imagine the villagers knew how the destructive havoc of a bolt of lightning. Likely they saw many homes that were destroyed that way. As a child, I can recall how terrified my Polish aunt was of lightning storms. Even though she didn’t live in a forest, her intense fear of lightning was obviously passed down through the generations. Polish prayer books often contain a prayer to say during storms.
