But in this decoration there is harmony. You have only to look at the picture to be sure of it. You cannot detect any rivalry between the three figures, although one of them is so much more massive than either of the other two. All of them seem drawn together into one chord of feeling, the leading note of which is the head of Prudence, lifted above the heads of her companions and seen alone against the open space of the sky and in the place of chief importance--the center of the arc of space. Please remind me presently to say a word about the placing of this head, for just now I do not wish to interrupt the subject that we are considering--the harmony of the composition.
