The name of G.E. Lessing (1766) is well known to all concerned with art problems. The ideas of Winckelmann reappear in Lessing, with less of a metaphysical tinge. For Lessing, the end of art is the pleasing, and since this is "a superfluous thing," he thought that the legislator should not allow to art the liberty indispensable to science, which seeks the truth, necessary to the soul. For the Greeks painting was, as it should always be, "imitation of beautiful bodies." Everything disagreeable or ill-formed should be excluded from painting. "Painting, as clever imitation, may imitate deformity. Painting, as a fine art, does not permit this." He was more inclined to admit deformity in poetry, as there it is less shocking, and the poet can make use of it to produce in us certain feelings, such as the ridiculous or the terrible. In his _Dramaturgie_ (1767), Lessing followed the Peripatetics, and believed that the rules of Aristotle were as absolute as the theorems of Euclid. His polemic against the French school is chiefly directed to claiming a place in poetry for the verisimilar, as against absolute historical exactitude. He held the universal to be a sort of mean of what appears in the individual, the catharsis was in his view a transformation of the passions into virtuous dispositions, and he held the duty of poetry to be inspiration of the love of virtue. He followed Winckelmann in believing that the expression of physical beauty was the supreme object of painting. This beauty exists only as an ideal, which finds its highest expression in man. Animals possess it to a slighter extent, vegetable and inanimate nature not at all. Those mistaken enough to occupy themselves with depicting the latter are imitating beauties deprived of all ideal. They work only with eye and hand; genius has little if any share in their productions. Lessing found the physical ideal to reside chiefly in form, but also in the ideal of colour, and in permanent expression. Mere colouring and transitory expression were for him without ideal, "because nature has not imposed upon herself anything definite as regards them." At bottom he does not care for colouring, finding in the pen drawings of artists "a life, a liberty, a delicacy, lacking to their pictures." He asks "whether even the most wonderful colouring can make up for such a loss, and whether it be not desirable that the art of oil-painting had never been invented." This "ideal beauty," wonderfully constructed from divine quintessence and subtle pen and brush strokes, this academic mystery, had great success. In Italy it was much discussed in the environment of Mengs and of Winckelmann, who were working there.
