Main articles: Prehistory of Corsica, History of Corsica, and Medieval Corsica The medieval influence of Pisa in Corsica can be seen in the Romanesque-Pisan style of the Church of Aregno. The origin of the name Corsica is subject to much debate and remains a mystery. To the Ancient Greeks it was known as Kalliste, Corsis, Cyrnos, Cernealis, or Cirné. Of these Cyrnos, Cernealis, or Cirné derive from a corruption of the most ancient Greek name of the island, "Σειρηνούσσαι" (meaning of the Sirens), the very same Sirens mentioned in Homer's Odyssey. The claim that latter Greek names are based on the Phoenician word for 'peninsula' (kir) are highly unlikely.
