Count the legend which was Ulises, the Greek hero, the founder of Lisbon. The proof of this would be that Lisbon, like Rome, is crossed by seven hills, which would surround the original town.
For this reason, the Greeks called the city Olissippo, name that would be an etymological derivation of the name of its founder. Since Greek times, the legend has remained present and was especially promoted by the Lusitanian writers of the Renacimiento. In fact, the myth has a very strong presence in You Luisíadas by Luís de Camões
The legend became theory when Theophile Cailleux, Belgian jurist of the s. XIX, made an exhaustive interpretation of Homeric geography, according to which Ulysses would have passed through Lisbon coming from the north, across the Atlantic. Ulises would have been in Lisbon before trying to turn it in the Cape Malea (which Cailleux associates with Cape St. Vincent) to reach Ithaca.
In any case, the foundation of Lisbon is necessarily prior, insofar as there is archaeological evidence that determines a former Phoenician presence.
Even for authors who already admitted that the myth was not solid, such as Eca de Queiroz, they kept a humanist version of the idea that affirmed that Ulysses did not found the physical place, but the spirit of the men of Lisbon. The myth of the founding of Lisbon is for Queiroz a sample of the values of the human condition in terms of imperfection. For other authors, such as happy man, the civic spirit and the voice of the exile. All this has to do with the depth of Fernando's philosophy Person in Portuguese culture, which takes legend as a constructive element of reality that forces man to take an active position in the history.
