We have a ton more numismatic, archeological, etc. evidence than Gibbon did.
I had documentary records more in mind.
Numismatic & archaelogical evidence add details, but don't do very much speaking. And can be a little distracting. I have seen more inane theories raised on them than I've seen them serving as useful additions or changes to knowledge. But academics need jobs.
Gibbon is far from the "last word" on the matter. But even though everybody and their dog has assaulted it with ferocity since the 18th C., it has held up remarkably well. Other scholars may have different interpretations of the facts, but the facts haven't changed.
In fact, I could say that about several monumental 19th C. histories. Grote, Mommsen, Gregorovius, Hodgkin, etc. They haven't really aged badly, their prose is excellent and are still much better reads than much of what the moderns put out. Can't say that for all. Some are quite flawed and skippable. But I find it surprising how several are still not improved upon in spite of a century of modern academic industry and "numismatic and archaeological" evidence. Some areas more than others, of course.
I guess it pays to be the "first" to write comprehensively about something. Everybody struggles to get out from under you shadow. And if your write properly, posterity is your bitch forever.
