even during alchemy, there was a strong belief that substances can be classified. However, the no- tion of element was a completely different one: the four elements Water, Fire, Earth and Air were described [...] his ele- ments into metals, non metals, earthly sub- stances, and simple substances. This organiza- tion is based on the properties of the elements: materials with similar behavior in chemical reactions [...] chemical elements that behave very similar to each other in reactions. He could find several combina- tions of elements, and there were always three elements. Moreover, these elements did not just react similarly
