The Spenserian Stanza is a stanza form invented by the English poet Edmund Spenser for his epic poem The Fairie Queene. Each stanza consist if eight lines of iambic pentameter or decasyllabic lines followed by one line in iambic hexameter or twelve syllables.
The rhyme scheme is as follows
ababbcbcc dedeefeff ghghhihii and so on
From Adonais: An Elegy on the Death of John Keats by Percy Bysshe Shelley
I weep for Adonais—he is dead!
Oh, weep for Adonais! though our tears
Thaw not the frost which binds so dear a head!
And thou, sad Hour, selected from all years
To mourn our loss, rouse thy obscure compeers,
And teach them thine own sorrow, say: “With me
Died Adonais; till the Future dares
Forget the Past, his fate and fame shall be
An echo and a light unto eternity!”
