To the sources of revenue which contributed to the prosperity of Pompeii we may add the presence of wealthy Romans, who, attracted by the delightful climate, built country seats in the vicinity. Among them was Cicero, who often speaks of his Pompeian villa (Pompeianum). That the imperial family also had a villa here is inferred from a curious accident. We read that Drusus, the young son of the Emperor Claudius, a few days after his betrothal to the daughter of Sejanus, was choked to death at Pompeii by a pear which he had thrown up into the air and caught in his mouth. These country seats, no doubt, lay on the high ground back of Pompeii, toward Vesuvius; they probably faced the sea. But the identification of a villa excavated in the last century, and then filled up again, as the villa of Cicero, is wholly without foundation. _Salve lucrum_, 'Welcome, Gain!' Such is the inscription which a Pompeian placed in the mosaic floor of his house. _Lucrum gaudium_, 'Gain is pure joy,' we read on the threshold of another house. A thrifty Pompeian certainly did not lack opportunity to acquire wealth. How large a population Pompeii possessed at the time of the destruction of the city it is impossible to determine. A painstaking examination of all the houses excavated would afford data for an approximate estimate; but the results thus far obtained by those who have given attention to the subject are unsatisfactory. Fiorelli assigned to Pompeii twelve thousand inhabitants, Nissen twenty thousand. Undoubtedly the second estimate is nearer the truth than the first; according to all indication the population may very likely have exceeded twenty thousand. This population was by no means homogeneous. The original Oscan stock had not yet lost its identity; inscriptions in the Oscan dialect are found scratched on the plaster of walls decorated in the style prevalent after the earthquake of the year 63. From the time when the Roman colony was founded no doubt additions continued to be made to the population from various parts of Italy. The Greek element was particularly strong. This is proved by the number of Greek names in the accounts of Caecilius Jucundus, for example, and by the Greek inscriptions that have been found on walls and on amphorae. The Greeks may have come from the neighboring towns; most of them were probably freedmen. In a seaport we should expect to find also Greeks from trans-marine cities; and, in fact, an Alexandrian appears in one of the receipts of Jucundus. There were Orientals, too, as we shall see when we come to the temple of Isis. Thus far there has come to hand no trustworthy evidence for the presence of Christians at Pompeii; but traces of Jewish influence are not lacking. The words _Sodoma_, _Gomora_, are scratched in large letters on the wall of a house in Region IX (IX. i. 26). They must have been written by a Jew, or possibly a Christian; they seem like a prophecy of the fate of the city.
