Dissertaçâo sobre as cores primitivas: com hum breve tratado de composiçao artificial das cores. Lisbonne, Regia officina typografica, 1788. In-8 (189 x 120 mm) de X, 148 pp., 1 f.n.ch. (errata), 2 planches dépliantes gravées dont une coloriée à l'époque; veau vert, double filet doré encadrant les plats, dos lisse orné, tranches dorées (reliure de l' époque). Édition originale. Important traité sur la théorie des couleurs. Divisé en deux grands chapitres, le théoricien de la couleur portugais Diogo de Carvalho y Sampayo (1750-1807) aborde dans un premier temps les couleurs simples, pour ensuite donner leur composition. Son influence sur le célèbre traité de Goethe Zur Farbenlehre est évidente et le poète scientifique allemand cite Carvalho y Sampayo dans son ouvrage (voir n°159). “In Goethe's Zur Farbenlehre one finds a general assessment of Carvalho e Sampayo's book Memoria sobre a formacao natural das cores... It is clear that research concerning the influences and contributions of Carvalho e Sampayo's work Zur Farbenlehre is required in parallel to a cross-comparative assessment of the methods used at the time for the study of color phenomena. By the eighteenth century, color involved academics, colour makers, and manufacturers as well as tradesmen, and there were already established industries in printing, ceramics, glass, textiles and color materials from painting. Furthermore color was also subject for theoretical pursuits in connecting with art, science and philosophical thought” (Leonor Ferrao, View on Eighteenth-Century Culture, p. 299). Bel exemplaire, bien complet des planches gravées, dont une coloriée, “that illustrate and elucidate the color system of Carvalho e Sampayo”. First edition of this important work by the Portuguese writer Carvalho y Sampayo which had exerted an influence on Goethe and his Farbenlehre, published in 1810. Complete copy, with the two engraved plates (one coloured), documenting the author's theories.
