Symbol Analysis
Ah, nature—a favorite topic among the Romantics. In the poem, the pleasure of being lazy is intensified by nature's pleasure, and the speaker seems to associate one with the other.
In the second stanza, the speaker enjoys the "blissful cloud of summer-indolence" (26) that leaves him, in line 28, feeling like he's wearing a "wreath of pleasure" (though, to be fair, the pleasure isn't intense enough to cause the wreath to bloom).
That isn't the only bit of natural imagery. In lines 43-44, our speaker spends a great deal of time using a nice day as a simile for his soul when it's allowed to be lazy:
My soul had been a lawn besprinkled o'er
With flowers, and stirring shades, and baffled beams. (43-44)
The sky reappears in the final stanza as the figures fade into the clouds. They are no match for the pleasures of a warm, lazy day.
