To write an effective ending to your essay, you should B. END ON A NOTE THAT'S LIKELY TO STICK IN THE READER'S MIND.
This is to ensure that your essay will still occupy the minds of your readers even after reading it.
Events or thoughts that readers can relate to your essay's end note will also bring back the ideas or thoughts you have stated in your essay.
You need to be able to write the myth in your own words. Libraries are a more modern idea that was not around in the Greek times.
If you would like to go in that direction anyway, why not rewrite the story of Athena and Arachnid but instead of weaving tapestries, have them write stories using thread to each write a book on cloth, much like the old-fashioned samplers. The "books" would hang on the wall in olympus and tell their stories, like a sampler. This inspired mortals to write stories for themselves and use murals, and papyrus to write upon and share their books, becoming the first library.
