Nor does the mischief of this attempt, which never accomplishes its intention, rest here: by this division of the work into many minute parts, the grandeur of its general effect is inevitably destroyed. Perhaps the only circumstance in which the Modern have excelled the Ancient Sculptors is the management of a single group in basso-relievo; the art of gradually raising the group from the flat surface, till it imperceptibly emerges into alto-relievo. Of this there is no ancient example remaining that discovers any approach to the skill which Le Gros has shown in an Altar in the Jesuits' Church at Rome. Different plans or degrees of relief in the same group have, as we see in this instance, a good effect, though the contrary happens when the groups are separated, and are at some distance behind each other. This improvement in the art of composing a group in basso-relievo was probably first suggested by the practice of the modern Painters, who relieve their figures, or groups of figures, from their ground, by the same gentle gradation; and it is accomplished in every respect by the same general principles; but as the marble has no colour, it is the composition itself that must give its light and shadow. The ancient Sculptors could not borrow this advantage from their Painters, for this was an art with which they appear to have been entirely unacquainted: and in the bas-relievos of Lorenzo Ghiberti, the casts of which we have in the Academy, this art is no more attempted than it was by the Painters of his age. The next imaginary improvement of the moderns is the representing the effects of Perspective in bas-relief. Of this little need be said; all must recollect how ineffectual has been the attempt of modern Sculptors to turn the buildings which they have introduced as seen from their angle, with a view to make them appear to recede from the eye in perspective. This, though it may show indeed their eager desire to encounter difficulties, shows at the same time how inadequate their materials are even to this their humble ambition. The Ancients, with great judgment, represented only the elevation of whatever architecture they introduced into their bas-reliefs, which is composed of little more than horizontal or perpendicular lines; whereas the interruption of crossed lines, or whatever causes a multiplicity of subordinate parts, destroys that regularity and firmness of effect on which grandeur of style so much depends. We come now to the last consideration; in what manner Statues are to be dressed, which are made in honour of men, either now living, or lately departed. This is a question which might employ a long discourse of itself; I shall at present only observe, that he who wishes not to obstruct the Artist, and prevent his exhibiting his abilities to their greatest advantage, will certainly not desire a modern dress.
