This is the modern flag of Macedonia. This one is only half of the ancient one, and is known as the Vergina Sun. Greece and Macedonia are embroiled in a controversy about the Vergina Sun. Both want to use it, and both claim it as their very own. I believe that I have seen a coin with Alexander the Great, and the sun symbol on it. The Greek passport watermark is the sun symbol. I did not know that anyone had a right to the symbol of the sun since it is so ancient, and found in almost every culture in some sort of depiction.
