Engraving from 'Mathematischer Atlas' (Mathematical atlas) by Tobias Mayer (1723-1762) published in Augsburg in 1745. Each plate has descriptive text on either side; some have contemporary hand colouring. Mayer was heavily influenced by Christian von Wolff's 'Anfangs-GrUnde aller mathematischen Wisenschaften', through which he had taught himself mathematics. This is apparent in the arrangement and content of Mayer's Atlas. The plates duplicate Wolff's choice of subjects - arithmetic, geometry, trigonometry, astronomy, geography, chronology, gnomonics, fortification, artillery, civil architecture, optics and mechanics. The atlas was published by the firm of Johann Andreas Pfeffel, for whom Mayer worked during his brief stay there from 1744 to 1746.
