There is no need to reproduce the Device of Prometheus bound, but simply to refer to it, and to note the allusions which Shakespeare makes to the mountain where the dire penalty was inflicted, “the frosty Caucasus.” From the Titus Andronicus we have already (p. 268) spoken of Tamora’s infatuated love,—

“faster bound to Aaron’s charming eyes

Than is Prometheus ty’d on Caucasus.”

John of Gaunt, Duke of Lancaster, endeavours, in Richard II. (act i. sc. 3, lines 275, 294, vol. iv. pp. 130, 131), to reconcile his son Henry Bolingbroke to the banishment which was decreed against him, and urges,—

“All places that the eye of heaven visits

Are to a wise man ports and happy havens.

Teach thy necessity to reason thus;

There is no virtue like necessity.

Think not the king did banish thee,

But thou the king.”
