Now note the radiating lines of the pavement. In a general way they repeat the radiation of the lines at the top of the picture; but they are farther apart and bolder, as befits the bolder character of the lower part. Have you discovered the point from which these lines of the pavement radiate? By using a straight edge to each in turn, you will find that all the lines, if continued would meet within the little circle of ornament that stands upon the altar. To this point also the gaze of many of the figures is directed.
