Hath more mysterious power, and birth more high;

And the deep horror chilling every vein

Owns them of stern terrific augury.

Beings of worlds unknown! ye pass away,

O ye invisible and awful throng!

Your echoing footsteps and resounding lay

To Cæsar’s camp exulting move along.

Thy gods forsake thee, Antony! the sky

By that dread sign reveals thy doom—“Despair and die!”[119]

[118] Cleopatra made a collection of poisonous drugs, and being desirous to know which was least painful in the operation, she tried them on the capital convicts. Such poisons as were quick in their operation, she found to be attended with violent pain and convulsions; such as were milder were slow in their effect: she therefore applied herself to the examination of venomous creatures; and at length she found that the bite of the asp was the most eligible kind of death, for it brought on a gradual kind of lethargy.—See Plutarch.
