The productions of such minds are seldom distinguished by an air of originality: they are anticipated in their happiest efforts; and if they are found to differ in any thing from their predecessors, it is only in irregular sallies and trifling conceits. The more extensive, therefore, your acquaintance is with the works of those who have excelled, the more extensive will be your powers of invention; and what may appear still more like a paradox, the more original will be your conceptions. But the difficulty on this occasion is to determine what ought to be proposed as models of excellence, and who ought to be considered as the properest guides. To a young man just arrived in Italy, many of the present painters of that country are ready enough to obtrude their precepts, and to offer their own performances as examples of that perfection which they affect to recommend. The modern, however, who recommends himself as a standard, may justly be suspected as ignorant of the true end, and unacquainted with the proper object, of the art which he professes. To follow such a guide will not only retard the Student, but mislead him. On whom, then, can he rely, or who shall show him the path that leads to excellence? The answer is obvious: those great masters who have travelled the same road with success are the most likely to conduct others. The works of those who have stood the test of ages have a claim to that respect and veneration to which no modern can pretend. The duration and stability of their fame is sufficient to evince that it has not been suspended upon the slender thread of fashion and caprice, but bound to the human heart by every tie of sympathetic approbation. There is no danger of studying too much the works of those great men: but how they may be studied to advantage is an inquiry of great importance.
