Gustave Flaubert said this quote
“ To return to antiquity [in literature]: that has been done. To return to the Middle Ages: that too has been done. Remains the present day. But the ground is shaky: so where can you set the foundations? An answer to this question must be found if one is to produce anything vital and hence lasting. All this disturbs me so much that I no longer like to be spoken to about it. ”
