In Satire 1.6, Horace depicts himself as a private citizen free to move around as he wishes in opposition to another character who does not enjoy such freedom of movement, owing to the fact that he is a politician. Seneca, in De clementia (perhaps recalling Horace), extols the freedom of movement he enjoys in the urban space thanks to the emperor, who, on the contrary, complains about the limitations imposed on him by his role. In Xenophon, Hiero, who was a private citizen before becoming a tyrant, is questioned by Simonides about the joys and woes of the two conditions: private citizens can go anywhere, while for tyrants everywhere they go is like travelling in enemy territory. In Horace’s sermo, the concrete space of the city refers to a potentially open political space: the figures we see moving around the streets of Rome are free to choose between political abstention and participation on the basis of their own personal inclinations. But the political and social situation was uncertain and unstable. Situations and characters tend in fact to transcend their immediate concreteness, referring to something else as well: something suited to satisfying the search for a principle of authority.
