Answer
The abrupt openings in Donne's work are indeed indicative of Mannerist techniques, a style that intentionally departs from traditional forms and techniques. It seeks to create a sense of surprise, disorientation, and even chaos, often through unexpected juxtapositions, distortions, and asymmetries. This approach reflects Donne's desire to challenge and subvert poetic conventions and create a unique, personal style that captures the complexities and contradictions of human experience.
