To the Noble, Honorable, Distinguished, Highly and Well-Wise, especially gracious brothers-in-law and respective godfathers, after offering my entirely willing services, I wish to humbly inform your noble and well-wise selves that, having observed how the first, second, and third parts of the Theatrum Machinarum Theater of Machines, which were brought together partly by the late Mr. Heinrich Zeising and partly by myself, but for the most part translated from foreign languages into our High German and submitted to public print by me, have been held dear and pleasant by many, I was thereby moved to now follow with the fourth part of said theater. This part deals with screw, pressure, turning, pressing, and lifting works, but primarily with the wonderful trispasto a complex pulley or lifting system, otherwise known as the screw without end, which has hitherto been little known in the German language, and has been translated into High German mostly from the Italian language by the honorable and highly learned Mr. Hieronymus Megiserus, Imperial Count Palatine and Electorate of Saxony Historian.
