Engraving of the Earth, including a diagram of its climactic zones (centre left), cardinal points (centre), and geographical features (bottom left). Illustration 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 work, through which he had taught himself mathematics. The plates duplicate Wolff's choice of subjects - arithmetic, geometry, trigonometry, astronomy, geography, chronology, gnomonics, fortification, artillery, civil architecture, optics and mechanics.
