Read it through once

Be thou the first true merit to befriend His praise is lost who stays till all commend Short is the date alas! of modern rhymes And 'tis but just to let them live betimes No longer now that golden age appears When patriarch wits survived a thousand years [479] Now length of fame (our second life) is lost And bare threescore is all even that can boast, Our sons their fathers failing language see And such as Chaucer is shall Dryden be So when the faithful pencil has designed Some bright idea of the master's mind Where a new world leaps out at his command And ready nature waits upon his hand When the ripe colors soften and unite And sweetly melt into just shade and light When mellowing years their full perfection give And each bold figure just begins to live The treacherous colors the fair art betray And all the bright creation fades away!
