In 1660 he made a great step forward in poetical craftsmanship by publishing _Astrœa Redux_, in celebration of Charles II’s return. The poem represents a complete reversal of the poet’s political opinions; but it is nevertheless a noteworthy literary advance. In its handling of the subject it shows a firmer grip and stronger common sense; in its style a new command of sonorous and dignified phrasing; and (as important a feature as any of the others) it is written in the heroic couplet. Methinks I see those crowds on Dover’s strand, Who in their haste to welcome you to land Choked up the beach with their still growing store, And made a wilder torrent on the shore. Here we see Dryden, though not yet at his best, coming to his own. The couplet marches with a steady but animated ring and swing. Its phrasing is apt and vivid; and it possesses a strength and music that are new. It marks the beginning of that adherence to the use of the couplet which was to be Dryden’s lifelong habit, and which was to mark a new epoch in our literature. Two other poems of this year--one on the coronation and one addressed to the Chancellor, Clarendon,--resemble _Astrœa Redux_ in their main features, and are little inferior. In 1666 he produced _Annus Mirabilis_, dealing with the extraordinary events of the year, particularly the Fire of London and the Dutch war. The poem is long, and often dull. When he attempts “style” he is sometimes florid and ridiculous. Moreover, the meter returns to the quatrain. The work is inferior to those of 1660, but is still an advance on the stanzas to Cromwell. For more than fifteen years succeeding this Dryden devoted himself almost entirely to the writing of plays. Then, about 1680, events both political and personal drove him back to the poetical medium, with results both splendid and astonishing. Political passions over the Exclusion Bills were at their height, and Dryden appeared as the chief literary champion of the monarchy in the famous satirical allegory _Absalom and Achitophel_ (1681). Absalom is the Duke of Monmouth, the unfortunate aspirant to the succession; and Achitophel is his daring but injudicious counselor Shaftesbury. These two are surrounded by a cluster of lesser politicians, upon each of whom Dryden bestows a Biblical name of deadly aptness and transparency. The satire is of amazing force and range, rarely stooping to scurrility, but punishing its victims with devastating scorn and a wrathful aloofness; and it takes shape in the best quality of Dryden’s couplet. Long practice in dramatic couplet-writing had now given Dryden a new metrical facility, tightening and strengthening the measure, and giving it crispness and energy without allowing it to become violent and obscure. We give a specimen of this measure, which in many ways represents the summit of Dryden’s poetical achievement:
