Ismene begs King Creon to spare her sister Antigone in the Forum of Paestum.
Antigone is a tragedy by Sophocles written before or in 442 BC. Family ties, social mores, and the king's law all clash. Antigone wants to bury her brother Eteocles, while King Creaon has decreed that his corpse be left to the vultures. Antigone disobeys him and gives her bother an honorable burial.
Doing the right thing sometimes means disobeying the king and those who fear him. And it does not always end well. He orders her to be buried alive. She instead opts for suicide with her beloved, the King's son Haemon.
It takes uncommon courage to stick to humanity's higher values.
