John Donne wrote the Holy Sonnets (also called Divine Meditations), a collection of 19 sonnets on themes of mortality, sin, divine love, and salvation. Famous lines include 'Death, be not proud' (Sonnet 10) and 'Batter my heart, three-person'd God' (Sonnet 14). Donne is the foremost Metaphysical poet, and the Holy Sonnets are his greatest devotional achievement.
