I think just because it's 2,000 years old doesn't mean it's been missing for 2,000 years? There could be references to a fragment as recently as 1,000 years ago

I think just because it's 2,000 years old doesn't mean it's been missing for 2,000 years? There could be references to a fragment as recently as 1,000 years ago, even if the contents of it were not recorded at that time. Or bad copy-editing.
