Late Roman Athenian lamp fabric (reddish brown, varied inclusions), firing (hard, black band through core), and surface (somewhat thick, slightly uneven, semiglossy slip, brownish red to purplish where thicker in relief).
Preservation comment
One large sherd preserves back right 25% of discus and adjacent shoulder and upper handle.
