Who is overrating Rome? Some history writers maybe. For any writer that praises Rome, you can find one that praises China, the Indus Valley/India, Egypt, Sumer, Greece, Persia, etc. Personally I like the Queen of Sheba's gig (Axum). Since the Queen of Sheba is a legend her exact kingdom is unknown, but for me it's Axum. Definitly in that general area anyway.
