What are the means by which Cleopatra died?

We simply do not know how Cleopatra died. There is a myth that she killed herself by snakebite, but that is only a myth. Octavian himself is the one who started it for political purposes. All the ancient writers (and modern ones too) disbelieve that she died by snakebite. They all believe it was some type of poison. Recently a study has been made determining that she died by a poison "cocktail" of three different poisons.
