More than 50 polished pyrite mirrors were found in prehistoric graves at the Snaketown site, a Hohokam site, in Arizona. Most were found burned and buried with cremated remains. Pyrite mirrors like these were most likely made in Central Mexico and traded north to the U.S. between AD 650 and AD 950. Keep in mind that in many prehistoric cultures your reflection was your soul. So a mirror like this was magical and a high status object.
