The Sign of Thunder - Fire Cross
The sign of thunder, known to western culture as the swastika, is one of the most ancient symbols in the world and has been used by all nations. The Latvian sign of thunder symbolizes light, fire, life, health and prosperity. No other nation has used the swastika so widely, nor developed so many variations of it as the Latvians
In folklore, the god of thunder, the heavenly blacksmith, is one of the most important deities. He ripens grain, and banishes demons with lightning. The dainas mention crossed lightning bolts, which are the most dangerous, since they set fire immediately to whatever they touch. Crossed bolts were depicted on a very old brooch. The fire cross can easily be developed from this pattern.
