Spenser, a jealous honorer of thine,
A forester deep in thy midmost trees,
Did last eve ask my promise to refine
Some English that might strive thine ear to please.
But, Elfin-poet, 'tis impossible
For an inhabitant of wintry earth
To rise, like Phœbus, with a golden quell,
Fire-wing'd, and make a morning in his mirth.
It is impossible to escape from toil
O' the sudden, and receive thy spiriting:
The flower must drink the nature of the soil
Before it can put forth its blossoming:
Be with me in the summer days, and I

 Una and the Lion  by Briton Rivière (1840-1920) from Book 1 of  The Faerie Queene 
 Spenser’s Spenserian stanza, his invention and the tool for crafting  The Faerie Queene  in all its lengthy glory, was described by several poets, including Wordsworth, as having a “lofty,” “floating,” “stately,” almost spiritual nature. This is because the intricate rhyme ( ababbcbcc ) always continues but the final line of each stanza (the last  c ) is an iambic alexandrine, also known as hexameter, and therefore has two extra syllables beyond the previous eight lines. This longer line slows the poem down and creates that lofty feeling, but it can (and is by both Keats and Shelley later) also be used to speed up the pace of a poem with the right choice of meter and enjambment.
