LOCOMOTION IN MAX 171 



is no doubt about the decision. Fig. Ill, for instance, 

 shows that a man in running assumes at certain 

 moments positions exactly like those represented in 

 the old masterpieces.* 



Fig. 111. — Instantaneous photograph of a runner : the position of the legs is the same 

 as that of tlie man on tlie extreme left of the toregomg illustration. 



It is quite easy to prove that runners never appear 

 in the positions adopted by certain modern artists, 



* One sometimes sees on a Greek vase a group of runners in the 

 most curious positions. It is a perfectly familiar fact that a man in 

 running or walking always swings the corresponding arms and legs in 

 opposite directions. The corresponding arm and leg move, so to speak, 

 in diagonal association. Now, on the Greek vase the arm and leg 

 belonging to the same side are represented as moving in the same 

 directions. Now, was this style of running, which is somewhat 

 suggestive of the ambling of quadrupeds, really practised on the 

 ancient race-course ? or is it a mistake on the part of the decorator 

 of the vase ? This is a question we are unable to answer. Such 

 a style of running is quite different from that n >w practised; yet 

 at the same time it does not appear physiologically impossible. It is 

 certainly a question worth considering.
