In mythology, what did Pandora open to release evil into the world?

The version I read, the box released all of the evil and when Pandora looked in the box, all that was left was hope, cowering in the corner.

I love this game! We're never too old to learn!

Quizard, Really? I though she released hope to combat all the bad things she had let loose.

I knew that without the clues.

I love 💕 a box

all was not bad , she did put back hope in the boxjar lol
