I don’t want to sound argumentative, but are you saying there are no modern poets who can write as eloquently as this? Sure, these are better than most people speak or write today, but it’s also a small selection of particularly good epitaphs, not a representative sample. We have some incredibly good writers today who can easily put these to shame, though they’ll be written in modern English. (Presumably these were translated from Latin though, but for some reason they chose to use thou instead of singular you, as is the norm for today.)
