The Roman columns all have radiused, ringed bases. Therefore not Roman.
Not ignorance .. Observation .. Take another look at all of your photographs.
Yes you are correct we identify and classify columns by their shape ...
Base, shaft and capitol.
I cannot find any roman columns anywhere that have shafts even resembling those examples at Mons Claudianus.
I'll continue looking .
You do likewise.
When you find one let me know.
