Three suns and a dragon

According to folk belief of the Bosnian people when the Earth was created there were three suns until one day a giant dragon swallowed up two and the third one was saved by a swallow. But, the dragon is immortal and he lives in the large sea in the east. Every morning when the sun appears the dragon opens his mouth and flies towards it, however he is prevented by an angel that strikes the dragon in the mouth with a thunder bolt and the dragon returns back into the sea. As soon as the dragon recovers he flies out of the sea and blows in the direction of the sun and then a wind is created form the mist and is dispersed all around the world.
