Donne (rhymes with "sun") was born in 1573 into a Roman Catholic family, and from 1584 to 1594 was educated at Oxford and Cambridge and Lincoln's Inn (this last a highly regarded law school). He became an Anglican (probably around 1594) and aimed at a career in government. He joined with Raleigh and Essex in raids on Cadiz and the Azores, and became private secretary to Sir Thomas Egerton. But in 1601 he secretly married Anne More, the 16-year-old niece of Egerton, and her enraged father had Donne imprisoned. The years following were years of poverty, debt, illness, and frustration. In 1615 he was ordained, perhaps largely because he had given up hope of a career in Parliament.
From the above information, the reader might conclude that Donne's professed religious belief was mere opportunism. But the evidence of his poetry is that, long before his ordination, and probably beginning with his marriage, his thoughts were turned toward holiness, and he saw in his wife Anne (as Dante had earlier seen in Beatrice) a glimpse of the glory of God, and in human love a revelation of the nature of Divine Love. His poetry, mostly written before his ordination, includes poems both sacred and secular, full of wit, puns, paradoxes, and allusions which are laden with the intense, condensed language that became the sign of the metaphysical poets. He represented amorous experience in religious terms and devotional experience in erotic terms, ultimately presenting a unified and sacramental view of the human condition.
After his ordination, his reputation as a preacher grew steadily. From 1622 until his death he was Dean of St. Paul's Cathedral in London, and drew huge crowds to hear his sermons, both at the Cathedral and at Paul's Cross, an outdoor pulpit nearby. Donne's extant sermons are one of our great Anglican treasures, for both their theological and literary value. His complex prose style is in some ways difficult for the modern ear to take in, but his theme continues to fascinate: "the paradoxical and complex predicament of man as he both seeks and yet draws away from the inescapable claim of God on him."
