In what distant deeps or skies

Burnt the fire of thine eyes?
On what wings dare he aspire?
What the hand dare seize the fire?

and

Tyger! Tyger! burning bright
In the forests of the night,
What immortal hand or eye
Could frame thy fearful symmetry?

Are "In what distant deeps or skies" and "Could frame thy fearful symmetry?" an example of alliteration?

To me, I think it is but I am not sure...

Yes.

d d in the first one

f f in the second

Thank you!

You're welcome.

No, "In what distant deeps or skies" and "Could frame thy fearful symmetry?" are not examples of alliteration. Alliteration refers to the repetition of the same consonant sound at the beginning of nearby words. In these lines from William Blake's poems "The Tyger" and "The Marriage of Heaven and Hell," respectively, there is no repetition of initial consonant sounds. However, both passages do use poetic devices such as rhyme, metaphors, and rhetorical questions to enhance their meaning and impact.
