Paternò is a town in the province of Catania, Sicily, southern Italy. The site of Paternò was settled before 3500 BCE. Its inhabitants were probably the Sicani, although it was located in mainly Sicel territory; its initial name was Inessa. The modern name derives form the Greek Paeter Aitnaion, meaning the "Fortress of the Etnaeans". The presence of another town, called Hybla Mayor or Galeatis, is attested north west to the current town.
