The scientific advancement claim is weird. It was also very slow during ancient Greek/Roman times and technological progress remained a somewhat foreign concept. Arguably European/Byzantine society was already quite a bit more advanced in many areas by the 1100s. And the dark ages ended with the Carolingian renaissance. If an ancient work copied by the 900s AD or so the chances that it survived until our day is relatively high, if not.. well it’s gone.
