Con el título "el arte industrial tardorromano", Aloïs Riegl abordó uno de los periodos más controvertidos de la historia del arte, un periodo considerado durante mucho tiempo como decadencia y falta de capacidad creadora. Riegl mostró de forma rigurosa que el arte tardorromano no es ni una prolongación residual ni un apéndice redundante en el arte romano.
