Machiavelli’s public life was largely occupied with events arising out of the ambitions of Pope Alexander VI and his son, Cesare Borgia, the Duke Valentino, and these characters fill a large space of The Prince . Machiavelli never hesitates to cite the actions of the duke for the benefit of usurpers who wish to keep the states they have seized; he can, indeed, find no precepts to offer so good as the pattern of Cesare Borgia’s conduct, insomuch that Cesare is acclaimed by some critics as the “hero” of The Prince . Yet in The Prince the duke is in point of fact cited as a type of the man who rises on the fortune of others, and falls with them; who takes every course that might be expected from a prudent man but the course which will save him; who is prepared for all eventualities but the one which happens; and who, when all his abilities fail to carry him through, exclaims that it was not his fault, but an extraordinary and unforeseen fatality.
