rt so conveniently situated
that he naturally coveted the possession of it. He invested it on all
sides by land, whilst its other enemies blockaded it by sea; so that the
city was reduced to famine. The partizans of John Visconti insinuated to
the Genoese that they had no other remedy than to place themselves under
the protection of the Prince of Milan. Petrarch was not ignorant of the
Visconti's views; and it has been, therefore, suspected that he kept
back his exhortatory epistle from his apprehension, that if he had
despatched it, John Visconti would have made it the last epistle of his
life. The morning after writing it, he found that Genoa had signed a
treaty of almost abject submission; after which his exhortation would
have been only an insult to the vanquished.

The Genoese were not long in deliberating on the measures which they
were to take. In a few days their deputies arrived at Milan, imploring
the aid and protection of John Visconti, as well as offering him the
republic of Genoa and all that belonged to it. After some conferences,
the articles of the treaty were signed; and the Lord of Milan accepted
with pleasure the possession that was offered to him.

Petrarch, as a counsellor of Milan, attended these conferences, and
condoled with the deputies from Genoa; though we cannot suppose that he
approved, in his heart, of the desperate submission of the Genoese in
thus throwing themselves into the arms of the tyrant of Italy, who had
been so long anxious either to invade them in open quarrel, or to enter
their States upon a more amicable pretext. John Visconti immediately
took possession of the city of Genoa; and, after having deposed the doge
and senate, took into his own hands the reins of government.

Weary of Milan, Petrarch betook himself to the country, and made a
temporary residence at the castle of St. Columba, which was now a
monastery. This mansion was built in 1164, by the celebrated Frederick
Barbarossa. It now belonged to the Carthusian monks of Pavia. Petrarch
has given a beautiful description of this edifice, and of the
magnificent view which it commands.

Whilst he was enjoying this glorious scenery, he received a letter from
Socrates, informing him that he had gone to Vaucluse in company with
Guido Settimo, whose intention to accompany Petrarch in his journey to
Italy had been prevented by a fit of illness. Petrarch, when he heard of
this visit, wrote to express his happiness at their thus
