A few years in my country, a critic caused some minor furore by suggesting that a beloved (and recently dead) author wasn't all that good. She had been a radio personality and children's literature writer for a generation, and her stories were a kind of sweet, homely social realism, about growing up in an apartment building and playing the violin, for instance.
Now the critic suggested that she had gotten chances others hadn't, because of her politics and identity. The public broadcaster at the time definitively saw shaping the country towards the labour party's social democratic vision as their job, and the author certainly fit nicely into that.
Now the point is, even if the critic is right and this author wasn't all that great, she can't just be swapped out for me. I grew up with those books, not anyone else's. So did a generation.
And so it is with all literature. Should we try to find the authors that got less attention at the time, but maybe would have deserved it? Maybe imagine what could have been? By all means. But what happened, happened. And it's even more important to understand those things.
Any cultural work subjected to that much thought and criticism becomes a mirror, or a lens, through which other subjects can be explored. Essays about Shakespeare written 100 years ago not only enrich our appreciation of Shakespeare, they reveal how people thought about things 100 years ago. The text of Shakespeare doesn’t change, so by observing changes in analysis of Shakespeare over time, we can reveal changes in our own culture over time.
You can’t do that with a new piece of writing, even if it were “new to us” despite being written contemporaneously with Shakespeare. It would be analyzed first in the context of Shakespeare, not by itself, because that is a context we all already share.
After Shakespeare's life, his works faded from prevalence, at least as represented in the printed record, until the mid-19th century. I'm uncertain of the specific dynamics, but suspect that growing cities and want of lowr-cost and popular known entertainment resulted in a revival of his plays (out of copyright, and hence free to produce).
Similarly, the Mona Lisa ascended to popular awareness and fame after it was stolen in the early 20th century, at a time when cheap mass-market newspapers existed, and photgraphic reproductions could be printed.

As for the Mona Lisa, have a look at least at https://gutenberg.org/files/2398/2398-h/2398-h.htm#leonardo .
Other than, say, that the term "Mona Lisa" doesn't appear at all in it, which would support my previous claim.
Gutenberg doesn't show the publication date. It appears to be 1873:
""" La Gioconda is, in the truest sense, Leonardo's masterpiece, the revealing instance of his mode of thought and work. In suggestiveness, only the Melancholia of Duerer is comparable to it; and no crude symbolism disturbs the effect of its subdued and graceful mystery. We all know the face and hands of the figure, set in its marble chair, in that cirque of fantastic rocks, as in some faint light under sea. Perhaps of all ancient pictures time has chilled it least.* As often happens with works in which invention seems to reach its limits, there is an element in it given to, not invented by, the master. In that inestimable folio of drawings, once in the possession of Vasari, were certain designs by Verrocchio, faces of such impressive beauty that Leonardo in his boyhood copied them many times. It is hard not to connect with these designs of the elder, by-past master, as with its germinal principle, the unfathomable smile, always with a touch of something sinister in it, which plays over all Leonardo's work. Besides, the picture is a portrait. From childhood we see this image defining itself on the fabric of his dreams; and but for express historical testimony, we might fancy that this was but his ideal lady, embodied and beheld at last. What was the relationship of a living Florentine to this creature of his thought? By means of what strange affinities had the person and the dream grown up thus apart, and yet so closely together? Present from the first incorporeally in Leonardo's thought, dimly traced in the designs of Verrocchio, she is found present at last in Il Giocondo's house. That there is much of mere portraiture in the picture is attested by the legend that by artificial means, the presence of mimes and flute-players, that subtle expression was protracted on the face. Again, was it in four years and by renewed labour never really completed, or in four months and as by stroke of magic, that the image was projected?
*Yet for Vasari there was some further magic of crimson in the lips and cheeks, lost for us.
The presence that thus rose so strangely beside the waters, is expressive of what in the ways of a thousand years men had come to desire. Hers is the head upon which all "the ends of the world are come," and the eyelids are a little weary. It is a beauty wrought out from within upon the flesh, the deposit, little cell by cell, of strange thoughts and fantastic reveries and exquisite passions. Set it for a moment beside one of those white Greek goddesses or beautiful women of antiquity, and how would they be troubled by this beauty, into which the soul with all its maladies has passed! All the thoughts and experience of the world have etched and moulded there, in that which they have of power to refine and make expressive the outward form, the animalism of Greece, the lust of Rome, the reverie of the middle age with its spiritual ambition and imaginative loves, the return of the Pagan world, the sins of the Borgias. She is older than the rocks among which she sits; like the vampire, she has been dead many times, and learned the secrets of the grave; and has been a diver in deep seas, and keeps their fallen day about her; and trafficked for strange webs with Eastern merchants: and, as Leda, was the mother of Helen of Troy, and, as Saint Anne, the mother of Mary; and all this has been to her but as the sound of lyres and flutes, and lives only in the delicacy with which it has moulded the changing lineaments, and tinged the eyelids and the hands. The fancy of a perpetual life, sweeping together ten thousand experiences, is an old one; and modern thought has conceived the idea of humanity as wrought upon by, and summing up in itself, all modes of thought and life. Certainly Lady Lisa might stand as the embodiment of the old fancy, the symbol of the modern idea. """
