So sweet the hour, so calm the time,
I feel it more than half a crime,
When Nature sleeps and stars are mute,
To mar the silence ev'n with lute.
At rest on ocean's brilliant dyes
An image of Elysium lies:
Seven Pleiades entranced in Heaven,
Form in the deep another seven:
Endymion nodding from above
Sees in the sea a second love.
Within the valleys dim and brown,
And on the spectral mountain's crown,
The wearied light is dying down,
This is one of the most poetic lines in this poem: there is alliteration ( S ee S ,  S ea,  S econd), as well as a homophone (“sea” and “see”). Not to mention, it is also in perfect iambic tetrameter form.
