The forehead, seen in front, is square; the nose, a little flattened--not by nature, but because, when he was a young boy, Torrigiano de' Torrigiani, a brutal and insolent fellow, smashed in the cartilage with his fist.
Michelangelo was carried home half dead on this occasion; and Torrigiano, having been exiled from Florence for his violence, came to a bad end.

The nose, however, being what it is, bears a proper proportion to the forehead and the rest of the face.

The lips are thin, but the lower is slightly thicker than the upper; so that, seen in profile, it projects a little.

The chin is well in harmony with the features I have described.

The forehead, in a side-view, almost hangs over the nose; and this looks hardly less than broken, were it not for a trifling proturberance in the middle.
