Burial soil on the surface of excavated objects at the Agora Excavations, Athens, Greece occasionally exhibits patterns that strongly resemble metal pseudomorphic textile structures. These soil structures can be present even without associated pseudomorphic corrosion. The resemblance of the soil to textile pseudomorphs suggests that the soil structures also represent a form of ancient textile preservation. Initial investigations are presented to raise the possibility that evidence for archaeological textiles may exist in this form. The textile/soil structures can be documented with enough detail to provide significant information regarding ancient textile production and use. Three preliminary case studies are presented: a Mycenaean albastron with a textile wrapping; textile remains associated with a 5th century BCE (Before Common Era) deposit; and a Classical paint palette cover. Probable fiber remains have been analyzed using Fourier transform-infrared spectroscopy (FT-IR) and found to be mineralized. However, mineralization does not seem to explain adequately the observed structures. Possible preservation mechanisms are discussed.
