"And the rivers swelling, blood in their silt, all for a linen undulation, a bit of cloud, a butterfly’s flicker, a wisp of swan’s down, an empty tunic — all for a Helen. And my brother? Nightingale nightingale nightingale, what is a god? What is not a god? And what is there in between them?" -George Seferis "Helen"
Pandora's Box-- The "box" was actually a large jar given to Pandora which contained all the evils of the world. When Pandora opened the jar, all its contents except for one item were released into the world. The one remaining item was Hope. Today, to open Pandora's box means to create evil that cannot be undone.
