Another Greek colony from Eretria had settled in the island of ISCHIA, which bore the Greek name Αἰναρία. It is a large extinct volcano, which, however, has repeatedly been active both in ancient and in modern times; for the island is remarkable for its internal fire, which is not yet quite extinct, and is still distinctly perceptible; hence it also contains hot springs; it is a truly paradise-like place on account of the fiery character of its whole nature, its soil, and its vegetation. The Greek colony afterwards disappears, and the island became Oscan simultaneously with Cumae. Between Ischia and the main land of Naples, there are several other islands, which were no doubt called PITHECUSAE. One of them is NESIS (the modern Nisita), that is, the little island (νησίς), a proof showing how early the modern Greek pronunciation of the η became prevalent. The ancients do not mention it.[40] Another island was PROCHYTA. All these islands had Eretrian colonies. DICAEARCHIA was a beautiful port, which was, no doubt, likewise taken by Campanians. After the capture of Capua, it came into the hands of the Romans, who established a Roman colony there, and called it PUTEOLI, though this name may have existed previously. The place then became the real port of Rome, for Ostia was bad, and the Portus Romanus on the right arm of the Tiber was not fit for sea-ships. The port of Puteoli, on the other hand, was naturally very beautiful, and even in the time of Augustus pains were taken to make use of the nature of the locality for the purpose of extending the port. Puzzolano, so excellent as a cement for water and harbour-works, was ready at hand in abundance, and in the greatest perfection. In the neighbourhood of Rome it is likewise found, but is not so beautiful; near Centumcellae, it was also employed in making the harbour, but it had to be conveyed thither from a distance. Its abundance in the neighbourhood led to the building of the molo of Puteoli. This _moles_ of Caligula is in reality not so mad a scheme as it is commonly described: it was suggested by the wishes of rational people, but its gigantic extent was the work of madness: when ever Caligula took up a good idea, he at once turned it into something irrational. The whole commerce and intercourse of Rome with her transmarine provinces at that time was carried on by way of Puteoli; and it was there that St. Paul landed, for the voyage along the coast from cape Misenum to the mouth of the Tiber was very dangerous. The ships of that period were in many respects excellent, but in others they were very deficient. It must be supposed that at Puteoli the ships were generally so far unladen as to enable them to sail into the Tiber at Ostia; they also found at Puteoli more easily than on the Tiber, advantageous cargoes to carry back. So long as commerce supplied only the actual wants, so that there was little or no speculation, it was carried on by means of large fleets, or,
