First edition of Diogo de Carvalho e Sampayo’s important treatise on colour theory which influenced Goethe’s famous work, Zur Farbenlehre.

In his 1788 book, the Portuguese nobleman and scientist Carvalho y Sampayo (1750–1807) describes his colour system, “the first fully coloured system of one-dimensional simple hue and tint/shade scales as well as a gray scale", in two main chapters. In the first chapter, he introduces its six simple colours (white, black, yellow, red, blue, and green), while in the second one, each simple colour is combined with the other five in three grades, resulting 15 linear scales with a total of 51 samples, presented in his book on a hand-coloured fold-out plate. Carvalho y Sampayo’s work served as a reference for Johann Wolfgang von Goethe who dedicated a chapter of his influential 1810 book, Zur Farbenlehre (Theory of Colours) to it. Alexander von Humboldt (1769–1859), who met Carvalho y Sampayo in 1799 during his stay in Madrid, was also familiar with Carvalho y Sampayo's work, and he even sent Goethe a letter, stating the similarity between the theory of both Goethe and the Portuguese scientist.
