absalom and achitophel

Of these the false Achitophel was first:
A Name to all succeeding Ages Curst.
For close Designs, and crooked Counsels fit;
Sagacious, Bold, and Turbulent of wit:
Restless, unfixt in Principles and Place;
In Power unpleas'd, impatient of Disgrace.
A fiery Soul, which working out its way,
Fretted the Pigmy Body to decay:
And o'r inform'd the Tenement of Clay.
A daring Pilot in extremity;
Pleas'd with the Danger, when the Waves went high
He sought the Storms; but for a Calm unfit
Would Steer too night the Sands, to boast his Wit.
Great Wits are sure to Madness near ally'd;
And thin Partitions do their Bounds divide;
Else, why should he, with Wealth and Honour blest,
Refuse his Age the needful hours of Rest?
Punish a Body which he could not please;
Bankrupt of Life, yet Prodigal of Ease?
And all to leave, what with his Toyl he won,
To that unfeather'd, two Leg'd thing, a Son;
