traced from Perrault’s bridge designs through L. Ch. Sturm up to I.P. Kulibin, the St.
Petersburg carpenter who „demonstrated“ the feasibility of his Neva bridge design by
loading tests on a scale model. A very similar approach is also presented by C. Walter
in his bridge treatise. Most of these attempts failed to employ the correct scaling laws,
and it was Leonhard Euler who set things right in a fascinating contribution in 1776
(Regula facilis pro diiudicanda firmitate pontis ... ex cognita firmitate moduli, Eneström
480) in reaction to Kulibin’s attempt. Euler’s approach was further popularized by the
Hungarian Jesuit and physicist Johann Baptist Horváth (Dissertatio de methodo
futuram pontis lignei ... firmitatam investigandi, 1780).
In summary, the architectural models of the Augsburg collection would deserve an
equally detailed analysis as the hydraulic machinery models in the same collection,
particularly because the model collection can be rooted in an intellectual environment
which is well documented by the publications of the two Caspar Walters and their
contemporary Lucas Voch (1728-83). The textbooks of these authors were reprinted
until the early 19 th century and had considerable impact on local practice. Today, the
models together with the preserved originals and the treatises provide a unique richness
of source material for the history of 18 th century architectural engineering.
