How did ancient cultures first discover iron? It fell from the sky. Early cultures used meteorites to craft weapons and jewelry long before anyone knew how to extract iron from ore.

Before maras learnt to smelt iron reliably, they (#spoiler) fashioned iron weapons out of meteorites, sometimes knowing about the existence of "celestial" metal. The #ArthdalChronicles2 writers did their research.

Heavy-metal space volcanoes may have forged gem-studded meteorites The tumult of the early solar system may have been even more metal than astronomers realized, a new theory suggests.
