(This poem was conceived and chiefly written in a wood that skirts the
Arno, near Florence, and on a day when that tempestuous wind, whose
temperature is at once mild and animating, was collecting the vapours
which pour down the autumnal rains. They began, as I foresaw, at sunset
with a violent tempest of hail and rain, attended by that magnificent
thunder and lightning peculiar to the Cisalpine regions.
The phenomenon alluded to at the conclusion of the third stanza is well
known to naturalists. The vegetation at the bottom of the sea, of
rivers, and of lakes, sympathizes with that of the land in the change
of seasons, and is consequently influenced by the winds which announce
it.—[SHELLEY'S NOTE.])
