the stanzas series refer to the poem by Shelley, the subtitles refer to his incidental residences in Italy and to poems he composed at these locations between 1818 and 1822.
'Poetry awakens and enlarges the mind itself by rendering it the receptable of a thousand unapprehended combinations of thought. Poetry lifts the veil from the hidden beauty of the world, and makes familiar objects be as if they were not familiar.' - P.B. Shelley
