problem from the outset. The construction of the Marly hydraulic machine, actually located in Bougival (where its inventor Rennequin Sualem died in 1708), driven by the current of the Seine moving fourteen vast paddle wheels, was a miracle of modern hydraulic engineering, perhaps the largest integrated machine of the 17th century. It pumped water to a head of 100 meters into reservoirs at Louveciennes (where Madame du Barry had her chateau in the 1760s). The water then flowed either to fill the cascade at Marly or drive the fountains at Versailles — the latter, after passing through an elaborate underground network of reservoirs and aqueducts. The machine could only deliver sufficient pressure to satisfy either Marly or Versailles, and invariably the King's demands received priority. In the nineteenth century, various other pumps replaced the originals, and the last was taken out of service in 1967.
