We may give a further word of mention to the voluminous Francis Quarles, who in his own day and long after enjoyed enormous popularity, especially among members of the Church of England and especially for his 'Emblems,' a book of a sort common in Europe for a century before his time, in which fantastic woodcuts, like Vaughan's 'Silex Scintillans,' were illustrated with short poems of religious emotion, chiefly dominated by fear. But Quarles survives only as an interesting curiosity. Three other poets whose lives belong to the middle of the century may be said to complete this entire lyric group. Andrew Marvell, a very moderate Puritan, joined with Milton in his office of Latin Secretary under Cromwell, wrote much poetry of various sorts, some of it in the Elizabethan octosyllabic couplet. He voices a genuine love of Nature, like Wither often in the pastoral form; but his best-known poem is the 'Horatian Ode upon Cromwell's Return from Ireland,' containing the famous eulogy of King Charles' bearing at his execution. Abraham Cowley, a youthful prodigy and always conspicuous for intellectual power, was secretary to Queen Henrietta Maria after her flight to France and later was a royalist spy in England. His most conspicuous poems are his so-called 'Pindaric Odes,' in which he supposed that he was imitating the structure of the Greek Pindar but really originated the pseudo-Pindaric Ode, a poem in irregular, non-correspondent stanzas. He is the last important representative of the 'Metaphysical' style. In his own day he was acclaimed as the greatest poet of all time, but as is usual in such cases his reputation very rapidly waned. Edmund Waller (1606-1687), a very wealthy gentleman in public life who played a flatly discreditable part in the Civil War, is most important for his share in shaping the riming pentameter couplet into the smooth pseudo-classical form rendered famous by Dryden and Pope; but his only notable single poems are two Cavalier love-lyrics in stanzas, 'On a Girdle' and 'Go, Lovely Rose.' JOHN MILTON, 1608-1674. Conspicuous above all his contemporaries as the representative poet of Puritanism, and, by almost equally general consent, distinctly the greatest of English poets except Shakspere, stands John Milton. His life falls naturally into three periods: 1. Youth and preparation, 1608-1639, when he wrote his shorter poems. 2. Public life, 1639-1660, when he wrote, or at least published, in poetry, only a few sonnets. 3. Later years, 1660-1674, of outer defeat, but of chief poetic achievement, the period of 'Paradise Lost,' 'Paradise Regained,' and 'Samson Agonistes.'
