Theodosius II the Roman emperor started a war with Iranians that lasted for 2 years. Before the war, the best Roman garrison was appointed to seize Derafsh Kaviani in order to demoralize the Iranian soldiers but all attempts failed. The flag was 50x70 centimeters, On top there's Farvahar, embossed figures are made using gold and silver and precious stones such as emerald and ruby are placed in a manner that the reflection of the sun is seen from far away as it's located on a hilltop during the wars. Three rows of soldiers in a circle protect it the whole time. Derafsh Kaviani once fell in the hands of enemy during the Ghadesiya war in 637 ending the Sassanid empire.
