oh yes I have read some of those. I think its a possiblity and old historians minds change like rusted shut gears move .along those lines I always thought that it was interesting that no one has ever done a study on pyrrhus's sicillia campaign to find out what influcence if any his troops might have had on Carthages units or local units . First time meeting a macedonian sysytem in the flesh or if they Carthage had any contact with the ptolemaic army etc . Everyone dimisses these possible cultural exchanges granted this is all possiblity but it took historians years to accept viking landings outside of europe proper .
