De Architectura. Venice: Giovanni Tacuino, 22 May 1511

First illustrated edition of Vitruvius’s Ten Books on Architecture, a landmark in the history of architecture. This is the only work on architecture to survive from antiquity. It was Vitruvius (ca. 90-20 BC) who famously declared that a structure must be durable, useful, and beautiful. His terms for order, arrangement, proportion, and fitness for purpose have guided architects for centuries. Vitruvius served in the campaigns of Julius Caesar, and he was involved in the restoration of Roman aqueducts. In ancient Rome, architecture encompassed not just the design of buildings but also civil and mechanical engineering, construction, military engineering, and urban planning.

Reports Regarding Sir William Thomson’s Compass and Sounding Machine. Glasgow: University Press [for Thomson], 1877

An important early offering brochure regarding the sale of the first modern compass and early navigational aids. This is a price list and an extensive collection of reports and testimonial letters from ship captains concerning Thomson’s sounding apparatus (the first to use wire instead of hemp) and compass. “The modern compass dates from 1876, when Sir William Thomson patented his dry-card compass” (Singer, History of Technology V). Thomson was deeply interested in the application of science to industry, and he apparently prepared this rare, ephemeral publication to promote his products, which helped to make him a wealthy man. This brochure includes a detailed price list for Thomson’s navigational instruments.
