Oh, the torment bred in the race,the grinding scream of death and the strong that hits the vein,the hemorrhage none can staunch, the grief,the curse no man can bear.But there is a cure in the house and not outside it, no,not from others but from them,their bloody strife, We sing to you, dark gods beneath the earth.Now hear, you blissful powers underground --answer the call, send help.Bless the children, give them triumph now. 

-- Aeschylus, The Libation Bearers, Harry Potter and the Deathly Hallows
