["It is useless to know what shall come to pass; it is a miserable
thing to be tormented to no purpose."
--Cicero, De Natura Deor., iii. 6.]

yet are they of much less authority now than heretofore. Which makes so
much more remarkable the example of Francesco, Marquis of Saluzzo, who
being lieutenant to King Francis I. in his ultramontane army, infinitely
favoured and esteemed in our court, and obliged to the king's bounty for
the marquisate itself, which had been forfeited by his brother; and as to
the rest, having no manner of provocation given him to do it, and even
his own affection opposing any such disloyalty, suffered himself to be so
terrified, as it was confidently reported, with the fine prognostics that
were spread abroad everywhere in favour of the Emperor Charles V., and to
our disadvantage (especially in Italy, where these foolish prophecies
were so far believed, that at Rome great sums of money were ventured out
upon return of greater, when the prognostics came to pass, so certain
they made themselves of our ruin), that, having often bewailed, to those
of his acquaintance who were most intimate with him, the mischiefs that
he saw would inevitably fall upon the Crown of France and the friends he
had in that court, he revolted and turned to the other side; to his own
misfortune, nevertheless, what constellation soever governed at that
time. But he carried himself in this affair like a man agitated by
divers passions; for having both towns and forces in his hands, the
enemy's army under Antonio de Leyva close by him, and we not at all
suspecting his design, it had been in his power to have done more than he
did; for we lost no men by this infidelity of his, nor any town, but
Fossano only, and that after a long siege and a brave defence.--[1536]
