comment on Tennyson's poetic style in "Tithonus"

The poem is a dramatic monologue spoken by Tithonus, primarily to his beloved, Eos, goddess of the dawn (Aurora in Roman myth). It is seven stanzas in blank verse, and its meter is iambic pentameter, perhaps reflecting the unnatural combination of mortal and immortal. There are no heroic (rhyming) couplets, unless one counts the two lines ending with the same word,

To dwell in presence of immortal youth,. Immortal age beside immortal youth,. And all I was, in ashes.
