Ithaca was, in Greek mythology, the island home of the hero Odysseus. The specific location of the island, as it was described in Homer's Odyssey, is a matter for debate. There have been various theories about its location. Modern Ithaca has traditionally been accepted to be Homer's island. One recent alternative candidate is Paliki, which may have been an island separated from the rest of Kefalonia, as argued by Bittlestone, Diggle and Underhill in Odysseus Unbound. This theory, however, has not been generally accepted on grounds of geology, archaeology, philology, or historical and Homeric analysis. “What is clearly missing,” wrote Dr Christine Haywood reviewing Odysseus Unbound, “is a good knowledge of the complexities of Homeric language, and the support of archaeology.”

Paliki is a peninsula and a former municipality on the island of Kefalonia, Ionian Islands, Greece. At the 2011 local government reform it became part of the municipality Kefalonia. In 2019 this municipality was divided into three municipalities, and the municipal unit Paliki became the only municipal unit of the new municipality Lixouri. The municipal unit has an area of 119.341 km2. The name comes from the ancient town of Pale/Pali, which was north of Lixouri and is now an archaeological site. The peninsula is the westernmost part of Kefalonia. The seat of the municipality was the town Lixouri (3,752).
