 and cannot escape it shakes the earth. This ex 

 planation is approved by others, too, as mentioned 

 a little above. Perhaps the crowd of witnesses

 Callisthenes, and he is a man not lightly to be 

 set aside. He was endowed with a lofty intellect, 

 and he dared to brave the wrath of a king. His 

 death is an eternal blot on the memory of 

 Alexander, which no valour and no success in

 rear has cut off its retreat, it is borne hither and 

 thither, and encountering itself in its course it
