Perhaps "rhyme" isn't the right word. There's a certain flow to the way some of the words are laid out. Part of that is the metre shaping the words possible but part of it also seems very deliberate.

It certainly doesn't have much of the last syllable rhyme you would expect today.

Alliteration and consonance are forms of (the broader definition of) rhyme.

It's interesting that rhyme detived from the word rhythm, but rhyme is the complement of rhythm.
