Strabo Geography 5.4.3

[3] Next in order after Latium is Campania, which extends along the [Tyrrhenian] Sea; above it is Samnium, in the interior, extending as far as the Frentani and Daunii; and beyond are the Daunii, and the other nations as far as the Strait of Sicily. We shall in the first place speak of Campania. From Sinuessa ¹ to Misenum ² the coast forms a vast gulf; beyond this is another gulf still larger, which they name the Crater. ³ It is enclosed by the two promontories of Misenum and the Athenaeum. ⁴ It is along the shores of these [two gulfs] that the whole of Campania is situated. This plain is fertile above all others, and entirely surrounded by fruitful hills and the mountains of the Samnites and Osci. Antiochus says that this country was formerly inhabited by the Opici, and that these were called Ausones. Polybius appears to consider these as two people, for he says that the Opici and Ausones inhabit the country around the Crater. ⁵ Others, however, state that it was originally inhabited by Opici and Ausones, but was afterwards seized on by a nation of the Osci, who were driven out by the Cumaei, and these again by the Tyrrheni. Thus the possession of the plain was much disputed on account of its great fertility. [They add that the Tyrrheni] built there twelve cities, and named the metropolis Capua. But luxury having made them effeminate, in the same way that they had formerly been driven from the banks of the Po, they were now forced to abandon this country to the Samnites; who in their turn fell before the Romans. One proof of the fertility of this country is, that it produces the finest corn. I allude to the grain from which a groat is made superior to all kinds of rice, and to almost all other farinacious food. They say that some of the plains are cropped all the year round; twice with rye, the third time with panic, and occasionally a fourth time with vegetables. It is likewise from hence that the Romans procure their finest wines, the Falernian, the Statanian, and the Calenian. That of Surrentum ⁶ is now esteemed equal to these, it having been lately discovered that it can be kept to ripen. In addition to this, the whole country round Venafrum, bordering on the plains, is rich in olives.
