““So when the faithful pencil has design'd 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 colours 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 colours the fair art betray, And all the bright creation fades away!””
