When you squint to look at the sun, the intense light will flare out and resemble a circle with wings.
It originated in Ancient Egypt.
By the time the ancient Assyrians used it, the symbol was already a popular symbol in the consciousness for power and a meaningful religious projection into art.
It was not only used by the Assyrians: it was also used broadly to represent other gods.
When it was adopted by the Zoroastrians, it came from this milieu.
The winged sun entered Europe's popular conscience with Napoleon's invasion of Egypt.
However, it had continued to be used by Zoroastrian communities.
From there, it has entered popular culture in the form of the Chrysler logo and other brands.
