Necklace and Nose Ornament, 150-200. Near Teotihuac?n?s largest palace is a temple ornamented with green-feathered serpents, symbols of the earth?s fertility. Beneath the temple were at least 120 human sacrifices, most men, many warriors, and some wearing greenstone ornaments like these, perhaps a set. The sacrifices may have consecrated the temple or a ruler?s tomb, or both.
