Simile in A Valediction: Forbidding Mourning

Text of the Poem 1
"compasses..."   (Text of the Poem)

Donne uses this simile to compare the lovers’ souls to the two legs of a compass. He is not talking about a traditional navigation tool here but rather a mathematical compass used to draw circles. The two feet of this compass are attached at the top, meaning even if they are apart, they are still connected and work as one unit.
