Events in the main sequence of the Odyssey (excluding the narrative of Odysseus's adventures) take place in the Peloponnese and in what are now called the Ionian Islands (Ithaca and its neighbours). Incidental mentions of Troy and its house Phoenicia, Egypt and Crete hint at geographical knowledge equal to, or perhaps slightly more extensive than that of the Iliad. However, scholars both ancient and modern are divided as to whether or not any of the places visited by Odysseus (after Ismaros and before his return to Ithaca) were real.
The geographer Strabo and many others came down squarely on the skeptical side: he reported what the great geographer Eratosthenes had said in the late third century BCE: "You will find the scene of Odysseus's wanderings when you find the cobbler who sewed up the bag of winds."
The journey of Telemachus to Pylos and Sparta no longer raises geographical problems. The location of Nestor's Pylos was disputed in antiquity; towns named Pylos were found in Elis, Triphylia and Messenia, and each claimed to be Nestor's home. Strabo (8.3), citing earlier writers, argued that Homer meant Triphylian Pylos. Modern scholarship, however, generally locates Nestor's Pylos in Messenia. The presence of Mycenaean ruins at the archaeological site of Ano Englianos, or Palace of Nestor, have greatly strengthened this view. The Linear B tablets found at the site indicate that the site was called Pu-ro ("Pylos") by its inhabitants.
