I’m assuming English is a second language for you, and I will piece together the author’s assumptions for you as best I can. Please forgive incorrect assumptions. It had been assumed that Homer’s “writings” were indeed written down by whoever was Homer. Whether Homer was one person, or a collection of writers collectively named Homer, is the subject of debate. But it has been widely assumed that it was initially written down, and not passed orally, because no one can remember that much. Turns out... So one dude makes recordings of more modern oral traditions, and concludes that Homeric writings very well could have been initially oral. And then the dude dies young and under mysterious circumstances. As personal commentary, the argument against passing the story orally forgets that just about all Buddhist writings started out as oral and not written (as one example). I hope that is helpful for you.
