Yes, they are beautiful... The shirt, the blouse are garments the folds of which yield simple planes and effects that, rightly rendered, are those of true sculpture. But there is something better still, and that is sackcloth. If I had clothed my 'Burghers of Calais' in sackcloth, they would certainly be more beautiful. I did not dare to. Some one else will do this and will succeed. It is sufficient to express an idea and leave it to its destiny.
