Overview

Archaeometric analysis reveals standardized molding in Sasanian stuccos versus variable Early Islamic techniques at Ctesiphon, indicating a shift toward less centralized production over time.

Key Points

  • To characterize the manufacturing technology, raw material origins, and organizational shifts in stucco architectural decoration at Ctesiphon across the Sasanian and Early Islamic periods.
  • Conducted an integrated archaeometric investigation of sixteen stucco objects (N=16) curated at the Metropolitan Museum of Art.
  • Analyzed structural and compositional features using optical microscopy, petrographic thin-section analysis, micro–X-ray diffraction (µXRD), and scanning electron microscopy with energy-dispersive spectroscopy (SEM–EDS).
  • Sasanian stuccos were predominantly manufactured using prefabricated molds with minimal hand-finishing, whereas Early Islamic artifacts displayed greater technological variation suggestive of decentralized workshop production.
  • Chemical analyses identified locally sourced evaporitic raw materials across all samples, showing no direct correlation to specific decorative motifs.
  • Detected phase markers—including bassanite, anhydrite, amorphous aluminosilicates, and combustion residues—demonstrated heterogeneous firing conditions typical of traditional gypsum kilns.
