Saint Cetteus (or Ceteus, also known as Peregrinus, Pelligrinus, Pellegrino) (d. June 13, 597) (Italian: San Cetteo, Ceteo) is the patron saint of Pescara. He was a bishop of the 6th century, elected to the see of Amiternum in Sabina (today the city of San Vittorino) in 590, during the pontificate of Gregory the Great. Although largely legendary, the Passio is probably correct in placing Cetteus' death at the time of the Lombard invasion.
