The poet's frenzy.

Zeal without prudence is frenzy. [ Proverb ]

Melancholy is the nurse of frenzy. [ William Shakespeare ]

Demoniac frenzy, moping melancholy. [ Milton ]

What frenzy dictates, jealousy believes. [ Gay ]

Anger is the fever and frenzy of the soul. [ Proverb ]

Frenzy, heresy, and jealousy, seldom cured. [ English Proverb, collected by George Herbert ]

The frenzy of nations is the statesmanship of fate. [ Edward Bulwer-Lytton ]

The poet's eye, in a fine frenzy rolling,
Doth glance from heaven to earth, from earth to heaven,
And, as imagination bodies forth
The forms of things unknown, the poet's pen
Turns them to shapes, and gives to airy nothing
A local habitation and a name. [ William Shakespeare, A Midsummer Night's Dream ]

To woo is a pleasure in a young man, but a frenzy in an old. [ Proverb ]

A wicked conscience mouldeth goblins swift as frenzy thoughts. [ William Shakespeare ]

Wickedness is a kind of voluntary frenzy, and a chosen distraction. [ Tillotson ]

When the tongue or the pen is let loose in a frenzy of passion, it is the man, and not the subject, that becomes exhausted. [ Thomas Paine ]

Madness is consistent, which is more than can be said for poor reason. Our passions and principles are steady in frenzy, but begin to shift and waver as we return to reason. [ Sterne ]

There is still a real magic in the action and reaction of minds on one another. The casual deliration of a few becomes, by this mysterious reverberation, the frenzy of many; men lose the use, not only of their understandings, but of their bodily senses; while the most obdurate unbelieving hearts melt like the rest in the furnace where all are cast as victims and as fuel. [ Carlyle ]
