Here comes the hammer: sheet objects from the Cenote Sagrado, Chichén Itzá
Abstract
A multi-stage archaeometric analysis was undertaken of 22 hammered metals recovered from the Cenote Sagrado at Chichén Itzá, Mexico. These objects include sandals, axe-monies and tweezers. All metals were examined with optical microscopy (vis-UV-IR) for comprehensive documentation and with pXRF for determination of bulk composition. Finer resolution analyses, including RBS, SR-XRD and SR-XRF, were conducted on particular objects. Eighteen objects are Cu-Au-based, while the axe-monies and tweezers are Cu-based. At least two sandals were finished with electrochemical replacement gilding. Secondary alterations to the metals, from indentations to wrinkles, suggest that the objects were re-fabricated over time. The presence of particular compositions and fabrication techniques indicates that objects continued to be deposited in the Cenote several centuries after the main occupation of Chichén Itzá (AD 750-1050).
