Thank you Fernando.....very well explained and really helps get this more into perspective. The comparisons of these various writers over time and disparities in their views and observations based on information at hand at the time certainly adds to more of a status quo in our understanding of these materials.
I think that is what is so vital here, to analyze and compare extant material which often either dispels or better qualifies information from earlier writers.
Remember, we all make misteakes !
All the best
