It opens with the lines: All humane things are subject to decay, And, when Fate summons, Monarchs must obey:[2] Written about 1678, but not published until 1682 (see 1682 in poetry), "Mac Flecknoe" is the outcome of a series of disagreements between Thomas Shadwell and Dryden.
The poem depicts Shadwell as the heir to a kingdom of poetic dullness, represented by his association with Richard Flecknoe, an earlier poet already satirized by Andrew Marvell and disliked by Dryden, although the poet does not use belittling techniques to satirize him.
Multiple allusions in the satire to 17th-century literary works, and to classic Greek and Roman literature, demonstrate Dryden's complex approach and his mastery of the mock-heroic style.
Dryden uses the mock-heroic through his use of the heightened language of the epic to treat the trivial subjects such as poorly written and largely dismissible poetry.
The juxtaposition of the lofty style with unexpected nouns such as 'dullness' provides an ironic contrast and makes the satiric point by the obvious disparity.
