 Several critics mentioned Bertin 's hands . Twentieth @-@ century art historian Albert <unk> described them as " powerful , <unk> ... grasping his thighs in a gesture ... projecting ... enormous strength controlled " . Some contemporary critics were not so kind . The photographer and critic Félix <unk> was harshly critical , and disparaged what he saw as a " <unk> bundle of flesh ... under which , instead of bones and muscles , there can only be intestines – this <unk> hand , the <unk> of which I can hear ! " Bertin 's hands made a different impression on the critic F. de <unk> , who remarked : " A mediocre artist would have modified them , he would have replaced those swollen joints with the cylindrical fingers of the first <unk> model ; but by this single alteration he would have changed the expression of the whole personality ... the energetic and mighty nature " .
