Laestrygonians, we are told by Homer were mythical giants encountered by Odysseus on his return journey to Ithaca.
Wikipedia tells us that “according to Thucydides (6.2.1.) and Polybius (1.2.9) the Laestrygones inhabited southeast Sicily. The name is akin to that of the Lestriconi, a branch of the Corsi people of the northeast coast of Sardinia (now Gallura). Later Greeks believed that the Laestrygonians, as well as the Cyclopes, had once inhabited Sicily.
“According to historian Angelo Paratico, the Laestrygonians were the result of a legend originated by the sight by Greek sailors of the Giants of Mont’e Prama, recently excavated in Sardinia. Earlier, Victor Bérard had also suggested Sardinia.
Some writers have also sought to attribute a historical reality to the Laestrygonians, often proposing locations very different to that of Thucydides and Polybius. Emmet Sweeney [700.23] has noted that Robert Graves who invariably placed the Greek myths in a Mediterranean setting, suggested that the home of the Laestrygonians was to be found in the far north of Europe, in the Land of the Midnight Sun!
Equally exotic is the suggestion from Gerard W.J. Janssen of Leiden University who places the voyages of Odysseus in the Atlantic(b). However, although he situates most of the places visited in the eastern Atlantic, he does claim(a) that Homer‘s Laestrygonians were to be found in Cuba, an interpretation supported by both Théophile Cailleux and Iman Wilkens.
