"Fragment Of A Rota In Egyptian Porphyry, Roman Period"
Fragment of a Roman Rota from the Egyptian porphyry period from a pavement, 1st-3rd century AD. Found in Ostia around 1900 and since then in a private Belgian collection. For a similar one see the book Porphyry by Dario Del Bufalo or the pictures from that book that I included.I guarantee that this object is old.
