Abstract:

A wooden coffin lid, of unknown provenance, with ground and colored layers and an ancient textile, was found at the Egyptian Museum basement in Cairo (JE 36806). The information obtained leads to the conclusion that the coffin lid dates back to the Ptolemaic period in Egypt (332-30 BC), whereas the textile does not belong to the coffin lid. Portable x-ray radiography, photography, optical microscopy, reflected light USB microscopy, Fourier transform infrared spectroscopy with attenuated total reflection (FTIR-ATR), energy-dispersive X-ray spectroscopy (EDX), X-ray diffraction (XRD) and Raman spectroscopy were used to assess the deterioration and the structure of the coffin lid and to understand how it was made in the necropolis workshop.
