I can't write the whole summary for you, but writing a summary is quite easy. Just take the main point of each chapter (in your case). Write the main point and what it caused. Kinda like cause and effect. Do this for each chapter. :) If you need anymore help, please feel free to ask! Hope this helps and have a Happy New Year!
A-Progressive tense Example: I bike everyday. "I am biking today."
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.
