He had been advised by a physician to live as much as possible in
the open air; and a fortnight of a bright warm July was spent in
tracing the Thames to its source. He never spent a season more
tranquilly than the summer of 1815. He had just recovered from a severe
pulmonary attack; the weather was warm and pleasant. He lived near
Windsor Forest; and his life was spent under its shades or on the
water, meditating subjects for verse. Hitherto, he had chiefly aimed at
extending his political doctrines, and attempted so to do by appeals in
prose essays to the people, exhorting them to claim their rights; but
he had now begun to feel that the time for action was not ripe in
England, and that the pen was the only instrument wherewith to prepare
the way for better things.
In the scanty journals kept during those years I find a record of the
books that Shelley read during several years. During the years of 1814
and 1815 the list is extensive. It includes, in Greek, Homer, Hesiod,
Theocritus, the histories of Thucydides and Herodotus, and Diogenes
Laertius. In Latin, Petronius, Suetonius, some of the works of Cicero,
a large proportion of those of Seneca and Livy. In English, Milton’s
poems, Wordsworth’s “Excursion”, Southey’s “Madoc” and “Thalaba”, Locke
“On the Human Understanding”, Bacon’s “Novum Organum”. In Italian,
Ariosto, Tasso, and Alfieri. In French, the “Reveries d’un Solitaire”
of Rousseau. To these may be added several modern books of travel. He
read few novels.
