This article presents reconstruction of Hellenist methodology formulated by Lucio Russo in his book 'Forgotten revolution'. Russo puts forward hypothesis that scientific method generally has its source in Hellenist period of antique Greece. The author argues that modern methodology often repeated discoveries of Hellenist Greek scholars. Good example of such a parallel are Hellenist phaenomena and their modern equivalents - protocol sentences in logical positivism. Methodological model of science formulated by Russo to explain history if science is based on three principles: theoreticality, deductiveness, and regularity. However, this definition seems a bit too narrow for Hellenist methodology and far too narrow for modern paradigms of sciences.
