The island of Capri is usually excluded, as it does not belong to the same geologic formations.
History
In the classical epoch, some Phlegraean Islands were called Pithecussae, the Greek Pithekousai (Πιθηκοῦσαι, ‘islands of monkeys’).
A Greek myth tells of two brigands, the Cercopes of Ephesus, who played pranks on Zeus, who then punished them by turning them into monkeys and exiling them to the islands of Aenaria (Ischia) and Prochyta (Procida).
Legend had the monster Typhon buried under Ischia, and the GiantMimas buried under Procida. Such stories might be significant as a clue to how the ancient Greeks attempted to account for the volcanism of the whole area. The resulting changes in the topography of the islands were due to the frequent intervention of deities.
