Golden version of Esfandyar
According to the epic Shahnameh, Esfandiyar was the Crown Prince and a Divine Warrior of ancient Iran (or Persia) who supported the prophet Zartosht (Zarathustra), enabling him to spread the religion of Zoroastrianism. He also fought against many apostates and enemies of Zartosht to do so. In return, Zartosht gave Esfandiyar a chain and armor from Heaven. The armor made him invincible and the chain had the power to bind anyone, even a demon or evil magician, making them unable to escape. Zartosht also gave a Divine blessing to the prince and declared that anyone who would spill the blood of Esfandiyar (killed him) shall suffer a cursed life of bad omens until the day he dies and even after death would be condemned to hell.
