Answer:
Autumn's golden reign- Personification
Rising radiance drives the shades away- Assonance
From star to star, the mental optics rove-Iambic Pentameter
Step-by-step explanation:
The first excerpt is alluding a physical or human attribute to an inanimate object which is saying that autumn has the human capacity to be on a golden reign.
An assonance is the repetition of identical or similar two or more stress vowel sounds. This assonance takes place with the words "shade" and "away".
An iambic pentameter is a line of verse with five metric feet that is made up of one short and long syllable.
"From star to star, the mental optics rove" makes use of iambic pentameter because of the first unstressed syllable which is followed by the stressed syllable.
