Let us gather and explore sacrifice protrayed in Myth/Religion and decide once and for all who gets the Gold. Here I give a couple of examples. Others can certainly be nominated. Let's start the show!
First down the catwalk is Jesus Christ. He is sporting a very skimpy andn quite revealing three days of death. Not much to start with, and he lessens his own value noticably by bragging his foreknowledge that he would rise from the grave, good as new, and be second in command in Heaven. Not much of a sacrifice, if you ask me, but he made it into the Show because his Daddy has a great deal of influence in certain circles.
Next is a real winner: Prometheus, creator of man and defender of mankind from the wickedness of a young Zeus. Not only did he teach us virtually everything needed to survive, but he stole fire for us when Zeus would see us shivering in the cold eating raw fish. He was punished for his misdeed by being chained to a pillar (or cliff, some say) for eternity. Not for three days, not for a week, but for eternity. On top of that, when he refused to give up his wisdom, Zeus send his pet eagle every day to eat his liver, which would then grow back overnight (he was the son of a Titan, after all), only to get eaten again the next day. All of this he was willing to suffer because he loved us that much.
Any other nominees?
