1. In "The Flea", Donne compares a flea that has bitten both him and his lover to a marriage bed:
>Oh, stay, three lives in one flea spare,
Where we almost, yea, more than married are.
2. In "A Valediction: Forbidding Mourning", Donne compares the parting of two lovers to the setting of the sun:
>Our two souls therefore, which are one,
Though I must go, endure not yet
A breach, but an expansion,
Like gold to aery thinness beat.
3. In "The Ecstasy", Donne compares the union of two lovers to the meeting of two compasses:
>So must pure lovers' souls descend
To affections, and to ends,
Of which our senses, till they rise,
Are neither instruments nor eyes.
4. In "Holy Sonnet XIV", Donne compares the soul's journey to heaven to a ship's voyage:
>Batter my heart, three-personed God, for you
As yet but knock; breathe, shine, and seek to mend;
That I may rise and stand, o'erthrow me, and bend
Your force to break, blow, burn, and make me new.
These are just a few examples of the many metaphysical conceits that can be found in John Donne's poetry. Donne's use of conceits is one of the things that makes his poetry so unique and memorable.
