Exotic Similes

John Donne is widely known for using the far-fetched similes, which adds a great flavor to his poetry. You pick any poem and you’ll find a simile, which is never used by any other poet the way Donne used it. For instance:

"So let us melt, and make no noise,/ No tear-floods, nor sigh-tempests move;/ 'Twere profanation of our joys/ To tell the laity our love." Their love is not the ordinary love of mere mortals. It is on a celestial level. The simile reveals how the love that the speaker and his beloved share is not merely sense-based, it transcends the physical. So, for them, being apart won't cause distress.
