Notwithstanding this pleasantry preceding the publication, he frankly acknowledges that the uncharitable spirit with which he was in consequence assailed, and the squabbles it drew him into with those of his own profession, and the dabblers in the arts, gave him greater uneasiness than was balanced by its general success. Thus does he express himself:-- "My preface and introduction to the _Analysis_ contain a general explanation of the circumstances which led me to commence author; but this has not deterred my opponents from loading me with much gross and, I think, unmerited obloquy; it therefore becomes necessary that I should try to defend myself from their aspersions. "Among many other high crimes and misdemeanours of which I am accused, it is asserted that I have abused the great masters. This is so far from being just, that when the truth is fairly stated it may possibly appear that the professional reputation of these luminaries of the arts is more injured by the wild and enthusiastic admiration of those who denominate themselves their fast friends, than by men who are falsely classed as their enemies. "Let us put a case: suppose a brilliant landscape had been so finely painted by a first-rate artist, that the trees, water, sky, etc. were boldly though tenderly relieved from each other, and the eye of the spectator might, as it were, travel into the scenery; and suppose this landscape, by the heat of the sun, the ravages of time, or the still more fatal ravages of picture-cleaners, was shorn of its beams and deprived of all its original brightness; let me ask whether the man who will affirm that this almost obliterated, unharmonious, spotty, patchwork piece of antiquity is in the state that it first came out of the artist's hands, does not abuse the painter?[52] and whether he who asserts that though it might once have been bright and clear it is now faded, does not thus place the defects to the proper account, and consequently defend him? "So far from attempting to lower the ancients, I have always thought, and it is universally admitted, that they knew some fundamental principles in nature which enabled them to produce works that have been the admiration of succeeding ages; but I have not allowed this merit to those leaden-headed imitators, who, having no consciousness of either symmetry or propriety, have attempted to mend nature, and in their truly ideal figures gave similar proportions to a Mercury and a Hercules.
