EXAMPLE
“…And to amase her weake, and pusill minde,
In creepe through crannies of imagination.
Deformd Idean formes, and phansies blinde.
Sent foorth by hir sicke sences, instigation.
Like staringe greisly fendes, threatninge invasion.
Presenting to her heart, the homely iarres.
And houshold cares, accurringe nuptiall warres…”
From: Eustathia, or the Constancie of Susanna
