Bis medium amplexi, bis collo squamea circum Terga dati, superant capite et cervicibus altis.[40] This description satisfies our imagination completely. The noblest parts of the body are compressed to suffocation, and the poison is aimed directly at the face. It furnished, however, no picture for the artist, who would show the physical effects of the poison and the pain. To render these conspicuous, the nobler parts of the body must be left as free as possible, subjected to no outward pressure which would change and weaken the play of the suffering nerves and laboring muscles. The double coils would have concealed the whole trunk and rendered invisible that most expressive contraction of the abdomen. What of the body would be distinguishable above or below or between the coils would have been swollen and compressed, not by inward pain but by outward violence. So many rings about the neck would have destroyed the pyramidal shape of the group which is now pleasing to the eye, while the pointed heads of the serpents projecting far above this huge mass, would have been such a violation of the rules of proportion that the effect of the whole would have been made repulsive in the extreme. There have been designers so devoid of perception as to follow the poet implicitly. One example of the hideous result may be found among the illustrations by Francis Cleyn.[41] The old sculptors saw at a glance that their art required a totally different treatment. They transferred all the coils from the trunk and neck to the thighs and feet, parts which might be concealed and compressed without injury to the expression. By this means they also conveyed the idea of arrested flight, and a certain immobility very favorable to the arbitrary continuance of one posture.
