|The Life of Marcus Antonius||Antony and Cleopatra|
|But Cleopatra was busied in making a collection of all varieties of poisonous drugs, and, in order to see which of them were the least painful in the operation, she had them tried upon prisoners condemned to die... She had her own physician, Olympus, to whom she told the truth, and asked his advice and help to put an end to herself||First Guard |
This is an aspic's trail: and these fig-leaves
Have slime upon them, such as the aspic leaves
Upon the caves of Nile.
That so she died; for her physician tells me
She hath pursued conclusions infinite
Of easy ways to die.
