Cleopatra had her servant tell Mark Antony that Cleopatra was dead. And so Mark Antony, he's already down, his soldiers have deserted him, there's no way for him to take on Octavian, he's essentially lost. And now Cleopatra, his lover, is apparently dead. He stabs himself repeatedly in the stomach. Now Cleopatra finds out about this, and then she has Mark Antony brought to him. He doesn't die immediately. Stabbing yourself in the stomach is a way of having a very slow and painful death.
