First edition of a thesis on the motion of falling bodies and pendula. This Thesis by Benno Ignatius von Heffstetten. It appears Joseph Zweissig and Nicolaus Tolent Fiechtmayr were professors overseeing the Thesis, but I am not certain.

Joseph Anton Zimmermann (1715-1797) was a Bavarian Engraver. The frontis for this work is by Zimmerman. It is unclear if Zimmerman also engraved the three plates. The Frontis is an allegorical portrait of Maximilian III Joseph, Duke of Bavaria.
