Os Lusíadas
Greek legend tells of Ulysses as the founder of Lisbon, Portugal, calling it "Ulisipo" or "Ulisseya", during his twenty-year errand on the Mediterranean and Atlantic seas. Olisipo was Lisbon's name in the Roman Empire. This folk etymology is recounted by Strabo based on Asclepiades of Myrleia's words, by Pomponius Mela, by Gaius Julius Solinus (3rd century AD), and will be resumed by Camões in his epic poem "Os Lusíadas" (first printed in 1572).
