This may be done in two ways. First, by effecting some change in the appearance of the creature inconsistent with its actual nature, as by giving it colossal size, or unnatural color, or material, as of gold, or silver, or flame, instead of flesh, or by taking away its property of matter altogether, and forming it of light or shade, or in an intermediate step, of cloud, or vapor; or explaining it by terrible concomitant circumstances, as of wounds in the body, or strange lights and seemings round about it; or by joining of two bodies together as in angels' wings. Of all which means of attaining supernatural character (which though, in their nature ordinary and vulgar, are yet effective and very glorious in mighty hands) we have already seen the limits in speaking of the imagination. Sec. 5. Or by inherent Dignity. But the second means of obtaining supernatural character is that with which we are now concerned, namely, retaining the actual form in its full and material presence, and without aid from any external interpretation whatsoever, to raise that form by mere inherent dignity to such a pitch of power and impressiveness as cannot but assert and stamp it for superhuman. On the north side of the Campo Santo at Pisa, are a series of paintings from the Old Testament History by Benozzo Gozzoli. In the earlier of these, angelic presences, mingled with human, occur frequently, illustrated by no awfulness of light, nor incorporeal tracing. Clear revealed they move, in human forms, in the broad daylight and on the open earth, side by side, and hand in hand with men. But they never miss of the angel. He who can do this has reached the last pinnacle and utmost power of ideal, or any other art. He stands in no need thenceforward, of cloud, nor lightning, nor tempest, nor terror of mystery. His sublime is independent of the elements. It is of that which shall stand when they shall melt with fervent heat, and light the firmament when the sun is as sackcloth of hair. Sec. 6. 1st. Of the expression of Inspiration. Let us consider by what means this has been effected, so far as they are by analysis traceable; and that is not far, for here, as always, we find that the greater part of what has been rightly accomplished has been done by faith and intense feeling, and cannot, by aid of any rules or teaching, be either tried, estimated, or imitated.
