Knowledge and labour in the alchemical lectures of Stephanus of Alexandria. Vangelis KOUTALIS, National Hellenic Research Foundation, Greece:
"Going back to the alchemical praxeis of Stephanus of Alexandria (7th century), who was the pioneer and by far the most influential representative of the Byzantine alchemical commentary tradition, we will examine how labour is signified, and how the relation between God and nature is defined, so as to ascertain resemblances and differences with the early modern chymical theories."
