I am a little disappointed the tomb where the mummy was found is from the time where Egypt was part of the Roman Empire. At this point ancient Egypt had been a colony of Rome for quite some time and beforehand a Greek/Macedonian colony for a few more centuries (under the Ptolemaic dynasty, founded by a general of Alexander the Great). If it was from a previous era, it would have been a much more interesting find (in my eyes).
The Iliad was written after the classical era of Bronze Age Egypt, so no classical age mummy could be buried with the Iliad because it didn't exist yet.
I think the point was that it would be a lot more interesting had it dated to a time prior to people for whom the Iliad was part of their culture were present in the region and when such artifacts would have been normal-ish
Finding american freed slave papers in a grave at Valley Forge -> ever so slightly interesting, we know those people were around there at that time.
Finding american freed slave papers in a grave outside an 1870s British encampment in Sudan -> very interesting how did this get here.
Or kind of like how finding Christian stuff in a roman grave varies a lot in implication by the year.
The article describes the veneration Roman -> (old) Greek -> (old) Egyptian and this finding appears to show that the veneration went both ways.
Frankly I can understand that: Homer really did smash out an absolute banger with Iliad. I might ask for a copy in my grave too, when the time comes.
The whole point of the article appears to be that when civilizations overlap, the "good old days" becomes a two way street (to gargle metaphors). I do find that interpretation very interesting and it fits in with my world view that history ("historia" - Latin for "story") is generally rather more complicated than many would like it to be to fit their current (or current as was) world view.
