Alchemical symbols on Stećak tombstones and their meaning
In order to truly be able to understand the phenomenology of Stećak tombstones in its total complexity, the Stećak primarily needs to be viewed through philosophy (Neoplatonism), theology (Cataphatic and Apophatic theology) and through the practice of theurgy and alchemy (work on stone and metal). It is very difficult to understand the symbols on Stećak tombstones without the essential knowledge of the basic principles and philosophy of Neoplatonism and Hermeticism, so even the most dedicated researchers of Bosnian Middle Ages observed Stečak symbols only as a decorative motifs denying the tombstones' enormous amount of "philosophical and spiritual content" that greatly can help in the study of the religious character of the Bosnian Church in the Middle Ages. To understand the meaning of many symbols of alchemy and theurgy on Stećak tombstones, a researcher of Bosnian medieval spirituality has to relate himself with one world in which mystery and spirituality are central. For example alchemical imagination constantly reminds us that opposing forces in nature have to unite thus forming a special relationships in a way that through their unification the mysterious "third" occurs (Alchemical "Egg","Philosopher's Stone", "Tree of Life") that transcends an ordinary existence.
