EARLY CLASSIC ARCHITECTURE BENEATH THE COPAN ACROPOLIS

Excavations beneath the Copan Acropolis provide the most complete record known for the origins and development of an Early Classic Maya royal complex (ca. a.d. 420–650). Beginning at the time of the historically identified dynastic founder, the earliest levels include the first royal compound, centered on a small talud-tablero platform, a vaulted tomb that may be that of the founder, and an adjacent tomb that may be that of the founders wife and dynastic matriarch. The timing and development of architecture provide evidence of the founding and growth of Copan as the capital of a Classic-period polity during the reigns of the first seven kings ( a.d. 426–544). By the reigns of Rulers 8–11 ( a.d. 544–628), the Early Classic Acropolis covered about the same area as its final version in the Late Classic. Documentation of specific Acropolis buildings provides evidence of the external connections that reinforced the authority of Copans Early Classic kings. Building sequences reflect the perpetuation of political power by using important locations as symbolic links to the sacred past. The Early Classic Acropolis also provides new evidence for the beginnings of palace architecture that have important implications for the origins of Maya state-level organizations. Overall, the findings from the Early Classic Copan Acropolis promise to significantly advance our understanding of the origins and development of Maya state systems.

Micro-Attenuated Total Reflection Spectral Imaging in Archaeology: Application to Maya Paint and Plaster Wall Decorations

Fourier transform infrared (FT-IR) attenuated total reflection (ATR) imaging has been successfully used to identify individual mineral components of ancient Maya paint. The high spatial resolution of a micro FT-IR-ATR system in combination with a focal plane array detector has allowed individual particles in the paint to be resolved and identified from their spectra. This system has been used in combination with micro-Raman spectroscopy to characterize the paint, which was found to be a mixture of hematite and silicate particles with minor amounts of calcite, carbon, and magnetite particles in a sub-micrometer hematite and calcite matrix. The underlying stucco was also investigated and found to be a combination of calcite with fine carbon particles, making a dark sub-ground for the paint.
