Original Article How to Create a Medical Knowledge: the Case of Georgius Baglivi (1668-1707) Zrinka Blažević1 1 History Department, Faculty of Humanities and Social Sciences, University of Zagreb, Ivana Lučića 3, Zagreb Abstract: Georgius Baglivi (1668-1707), Italian scientist of Ragusan origin, who worked as second physician to Pope Innocent XII and professor of anatomy and theoretical medicine at the College of Sapienza in Rome, was one of the first promotors of the fibre medical theory. Strongly influenced by Santorio Santorio’s iatrophysics, Baglivi conceptualised and propagated a “third path” between humoral and solidist medicine which explained all physiological and pathological processes by the living properties of fibres. In addition to this, Baglivi advocated a (Neo)methodist theory which stated that life and health were determined by the physical balance of the active solids (fibres) and the more passive fluids of the body. Despite his distinguished institutional status and professional prestige, Baglivi’s medical OPEN ACCESS theories, especially those concerning the function of the dura mater, were not unanimously accepted by his colleagues. Therefore, the interpretative focus of this article will be directed at Baglivi’s last work Correspondence: Canones de medicina solidorum ad rectum statices usum (Leiden, 1707) which is accompanied by three Zrinka Blažević [email protected] treatises in epistolary form dedicated to the Dutch botanist and professor of medicine, Peter Hout- orcid.org/ 0000-0003-3261-4333 tuyn (1648-1709).

S osloncem na teorijsko-metodološke uvide retorike znanosti, u radu će se nastojati osvijetliti literarne tehnologije, tj. suptilne diskurzivne strategije koje je Baglivi koristio kako bi oblikovao i legitimirao svoj sustav medicinskoga znanja te kreirao osobni habitus baroknog erudita. Na taj način će se na Baglivijevu slučaju pokazati kako su mehanizmi i modaliteti proizvodnje znanja i oblikovanja znanstvenoga habitusa bili čvrsto isprepleteni s procesima akumulacije i distribucije znanstvenoga kapitala unutar ranonovovjekovne res publica literaria.
