A commentary on the passage (Book 1, ll

A commentary on the passage (Book 1, ll. 66-93; given at the end) from "The House of Fame" by Geoffrey Chaucer?

some directions for the commentary:
1. Identify the passage and situate it. Mention the focus of your commentary.
2. Main part of the commentary: comment on the thematic engagements and language used to pursue them: what words rhyme together, is there alliteration, are there words repeated, rhetorical devices deployed in the passage, words that have several possible meanings and may therefore be interpreted in different ways? How are the themes developed? What is the effect on the reader?
3. Comment on the relationship between your passage and other moments in the text/other sources and extend your discussion beyond the passage itself.

the passage:
But at my ginninge, trusteth wel,
I wol make invocacioun,
With special devocioun,
Unto the god of slepe anoon,
That dwelleth in a cave of stoon
Upon a streem that cometh fro Lete,
That is a flood of helle unswete;
Besyde a folk men clepe Cimerie,
Ther slepeth ay this god unmerie
With his slepy thousand sones
That alway for to slepe hir wone is --
And to this god, that I of rede,
Prey I, that he wol me spede
My sweven for to telle aright,
If every dreem stonde in his might.
And he, that mover is of al
That is and was, and ever shal,
So yive hem Ioye that hit here
Of alle that they dreme to-yere,
And for to stonden alle in grace
Of hir loves, or in what place
That hem wer levest for to stonde,
And shelde hem fro poverte and shonde,
And fro unhappe and eche disese,
And sende hem al that may hem plese,
That take hit wel, and scorne hit noght,
Ne hit misdemen in her thoght
Through malicious entencioun.
