570-2. THE TRINITY, WITH ANGELS ADORING.
Orcagna (part of the altar-piece, 569).
One may notice here one of Orcagna's limitations. "He was unable to draw the nude. On this inability followed a coldness to the value of flowing lines, and to the power of unity in composition; neither could he indicate motion or buoyancy in flying or floating figures" (On the Old Road, i. § 78). Compare especially the flying angels in the two little pictures 571 and 572, with such figures as those by Botticelli (1034), and it will be seen at once how inferior Orcagna's knowledge was.
