poetry is to inspire a love for virtue.[30] He follows the example of Winckelmann in introducing the concept of ideal beauty into the doctrine of figurative art: "expression of corporeal beauty is the aim of painting: therefore supreme beauty of body is the supreme aim of art. But this supreme beauty of body is found in man only, and for him it exists only through the ideal. This ideal may be found among the brute creation in inferior degree; but is entirely absent from vegetable or inanimate nature." Landscape and flower painters are not really artists because "they imitate beauties possessed of no ideal: whereby they work by eye and hand alone, genius having little or no part in their compositions." Nevertheless, Lessing prefers a landscape painter to "the painter of historic pieces who, instead of making beauty his aim, merely depicts a crowd in order to show his cunning in simple expression, not in expression subordinate to beauty."[31] The ideal of bodily beauty then consists "chiefly in the ideal of form, but also in that of texture of the flesh, and in that of permanent expression. Mere colouring and transitory expression have no ideal since nature herself has placed no indelible seal upon them."[32] At the bottom of his heart Lessing dislikes colour; and when he finds the pen-sketches of painters showing "a life, a freedom, a brilliancy never to be found in their painted pictures," he asks himself "whether the most marvellous colouring can compensate so heavy a loss," and whether it is not to be wished "that painting in oils had never been invented"?[33] [Sidenote: _Theorists of ideal beauty._] Ideal beauty, that curious alliance between God and the subtle outline traced with pen or graver, that cold academical mysticism, came into fashion. In Italy (the home of Winckelmann and Mengs, who published many of their works in Italian) it was much discussed by artists, antiquaries and connoisseurs. The architect Francesco Milizia professed himself a follower of "the principles of Sulzer and Mengs";[34] the Spaniard d'Azara, living in Italy, edited and annotated Mengs, adding his own definition of beauty: "The union of the perfect and the pleasing made visible";[35] another Spaniard, Arteaga, one of the many Jesuit refugees in Italy, wrote a treatise on _Ideal Beauty_ (1789);[36] the Englishman Daniel Webb on coming to Rome and making the acquaintance of Mengs seized upon the ideas he heard him express on beauty, collected them and actually published them in a book anticipating Mengs' own.[37] [Sidenote: _G.
