The Swastika (卍) is widely found from the east to the west, from prehistoric times, to the extent that tens of thousands of pieces have been identified. There have been numerous views on the meaning or origin of the swastika. This paper argues that the swastika was originally a symbol of the air or wind god in Oriental civilization, and that it could have been applied to the ancient Mediterranean regions where cultural exchange and sharing with the Orient were active. Looking at the swastika from this point of view, it could represent all the previous views: the wind or air god could be represented as a personification, could come out with various animals on land or sea, could be expressed like a whirlpool, and was closely related to the sun and the moon. Wasn’t it a natural attempt to symbolize the air or wind that was thought to be the highest deity and the most basic cosmic element? And then, wasn’t it hard to find a more fitting symbol of the wind blowing in all directions or of the air and wind filling the universe, than the swastika pattern. Above all, the swastika’s shape basically resembles a whirlpool of wind, and even a toy wind vane.
