Write about one imagine John Donne uses in “at the round earths imagined corners.”

The line mentioned at the beginning of the poem about the imagined corners of the Earth refers to the map-making during the time it was written. It was a recurring idea to have imagery of angels at the corners of the maps showing the Earth.

The poem ends with the imagery of a blood seal to describe the significance of repentance. It is a contrasting image connecting the tangible with the intangible and it represents the individual’s confliction between his existence in the world and his religious beliefs.
