Peter Toth: A monumentális építészet hajnala Szlovákiában
After an extensive deforestation an open landscape originated, which could affect the overpopulation of wild game (Pavúk — Karlovskÿ 2004, 259). The occurrence of rondels in temperate Middle European zone is certainly not accidental. In terms of Neolithic agriculture the building of rondels was mostly affected by a climate change. An existential importance was the ability to predict the season changes and to find an optimal sowing date. In areas laying south, particularly Eastern Mediterranean, Anatolia and south-eastern Europe were the crucial agricultural periods (as today) considerably shifted compared to the Middle Europe. The areas laying north still remained in a hunter-gatherer's way of life. Therefore in these territories "the rondel calendar" would not function properly at the time of spring sowing (Pavúk — Karlovskÿ 2004, 265-266; 2008, 497). The end of celestial temples Theendofastronomicallyorientedrondelarchitecture in Middle Europe in the middle of the 5th millennium BC indicates, that necessary astronomical observations, which were undoubtedly constantly further improved, were performed by other, architectural and constructional less demanding way. The circle, which was used in connection with the astronomical orientation and natural calendar systems and Lengyeli kultúrához tartozó kerámia, Bucany (Pazinová 2012, obr. 4. után). Lengyel culture pottery from Bucany (after Pazinová 2012, obr. 4). chronometry, represented an optimal shape and eventually evolved into a clock-face of sun and mechanical clock (Pavúk - Karlovskÿ 2004, 258).
