Devotional poetry of the 17th century explores themes of faith, love, and mortality through intricate metaphors and paradoxes. Poets like John Donne, George Herbert, and Henry Vaughan grappled with personal spirituality amid religious upheaval and scientific advancements. These poets used metaphysical conceits and simple language to express complex theological ideas. Their works reflect the tension between earthly and divine love, the soul's journey towards God, and the struggle between faith and doubt.
