What are some pieces of literature that were hailed as masterpieces in their times, but have failed to maintain that position since then?

It feels like a lot of stuff that used to be called “instant classics” just sort of disappears later. I bring it up because when people talk about 19th-century British literature, it’s usually the same few authors—unless you’re really going deep into the period. There were surely lots of works that came out and were praised at the time, but I guess some of them just lost their shine or don’t seem important to later generations anymore.
