Machiavelli explains the success of princes by referring to their virtú, or prowess which overcomes the vagaries of fortune. I pay attention to the meaning of virtú, which some commentators claim to be a clear and understandable term while others deny this. If virtú is defined in terms of fortune, we have reasons to be skeptical. The problem is that fortune is a concept of many meanings in The Prince. Some of these are mythological, such as the goddess Fortune and fortune as a woman. Machiavelli seems to use the concept of fortune in four different ways: resource, fate or destiny, chance, and uncertainty. I will provide evidence for this thesis as I analyze these ideas and try to relate them to each other. The Prince is a conceptually loose treatise.
