John Milton (1608–1674) is considered to be among the most learned of all English poets. After graduating from Cambridge, Milton undertook six years of self-directed study in theology, philosophy, history, politics, literature, and science. He then spent several years writing pamphlets for the Puritan and Parliamentary causes. His incessant labors setting the typeface eventually led to blindness. His masterpiece, Paradise Lost, was composed in memory and dictated to a scribe.
