Overall, John Donne's poem 'Death Be Not Proud' is a masterful argument against the power of Death. The theme, or the message, of the poem is that Death is not some all-powerful being that humans should fear. Instead, Death is actually a slave to the human race and has no power over our souls....DEATH be not proud, though some have called thee Mighty and dreadful, for, thou art not so, For, those, whom thou think'st, thou dost overthrow, Die not, poor death, nor yet canst thou kill me. ... The official name of this poem is “Divine Sonnet X,” although is it most frequently called by its first line.
