Contributing to the advancement of scientific technology were the printed papers and illustrated books of the day. They were also the primary method of transferring practical hydraulic facts and fountain design ideas all through Europe. An un-named French water feature developer was an internationally famed hydraulic pioneer in the late 1500's. By designing gardens and grottoes with built-in and ingenious water attributes, he started off his career in Italy by getting imperial mandates in Brussels, London and Germany. The publication, â€œThe Principles of Moving Forces,â€ penned near the end of his life in France, became the definitive text on hydraulic mechanics and engineering. Updating vital hydraulic breakthroughs of classical antiquity, the book also explains contemporary anchor hydraulic technologies. Archimedes, the inventor of the water screw, had his work featured and these included a mechanical means to move water. Natural light heated up the water in a pair of undetectable vessels adjacent to the ornamental water feature were displayed in an illustration. The end result: the water fountain is triggered by the hot water expanding and ascending up the pipes. Models for pumps, water wheels, water features and outdoor ponds are also included in the book.
