I am terrible at grocery shopping. I went to two different grocery stores to buy pasta sauce. Hours later with a full fridge and cabinets, guess what I don’t have.
Guess.
The Heel
Achilles doesn’t die in the Iliad. He’s alive at the end, now the greatest of the Achaeans and therefore doomed. Yet he is alive. The deal with the heel, with his mother dipping him into the river Styx, none of that appears in Homer. It isn’t in the Iliad; it isn’t in the Odyssey.
It’s basically in the fanfiction.
