Another recommendation from Paul Rumsey (thanks, Paul!), these are from a series of lithographs dated 1842–43 by Leopold Müller based upon paintings (?) by Giovanni Battista Pian, or Giovanni Battista de Pian (1813–1857). Shades again of (Giovanni Battista) Piranesi in the name, although the pictures are a lot less Piranesian than Antonio Basoli’s; the only time Piranesi bothered with wooden materials was as a support for building stone arches, and in the spars and torture engines of his Prisons. See more of the series here.
