Erazm Sykst i jego koncepcje hydrogeologiczne

Erasmus Sixtus was a remarkably educated physician, social activist and Lvovian municipal dignitary. His “opus magnum” entitled: “About the Szkło Hot Springs” is a book in which he at large discusses questions of spa medical treatment as well as problems of Szkło spring water origin, movement and quality. Although his considerations are based mainly on concepts of antique and medieval philosophers as well as Renaissance physicians, some ideas concerning groundwater origin, and movement, the causes of its high temperature in case of hot springs, contain rudiments of modern hydrogeological thought.
