Rome vs Han essay- want get some opinions

[Virilis]

IIRC it was Livy who expressed the horror of the Greeks at all the severed limbs the Romans left strewn on a Macedonian battlefield.

This has always puzzled me. I know that the macedonians didn`t use the cavalry as effectively as in the times of Alexander anymore, but how about the swords? How could the macedonians be horrified by the cutting capabilities of the roman swords? Didn`t they have KOPIS anymore (which is a cutting weapon par excellence)? Also the longer bladed Xiphos could have been also a very efficient cutting weapon....

Perhaps this is again a question of culture, Rome`s relentless style of making war. Perhaps the macedonians were horrified by the brutality of roman battle tactics in general, mutilating bodies etc.?
