There are significant differences and aspects of similitudes between the Kassel Apollo and the Doryphoros in the slide one. The features exhibited by the two nude males act as a correspondence of the Early and the High Classical periods in the history of Greek arts and paintings. The nude man standing in the first image (Apollo Kaiser), has distinct features of this generation, which invokes the feelings and strength of arts in the early classical period. The man standing is one bare foot embedded on the ground. The position and posture of this man suggests that he is stationary, or firmly fixed on the ground. On the other hand, Doryphoros of the high classical period gives an expression this generational art and features (Moon, 1995). Based on the second image of the firs slide, the image gives an ideal proportion of human figure. Therefore, the nude man has all body parts in a measure of proportionality thus giving a clearer impression of human body compared to the fits image of the early classical era. Thus, the two parts have spatial attributes in the value of measured proportionality of human body parts.
The next aspect of comparisons refers to the symmetry in the head and posture of these images. The first image shows a nude man with somehow rubber banded hair, while the second image gives a clear impression of a nude man having a natural hair. The distinction in the hair gives a sense of stylistic standards of both generations (Moon, 1995). Besides, the posture exhibited by the two nude men givens one point of commonality, since the weight is seemingly distributed on the lags.
Finally, the two images show different styles of the two classical generations. In the first image, the man is posted as stationary with some his feet broken. The second image by Doryphoros gives man an impression of movement. This is yet another difference attributed to the arts between the early and classical periods.
