Of the other cities of Latium, some are distinguished by a variety of remarkable objects, others by the celebrated roads which intersect Latium, being situated either upon, or near to, or between these roads, the most celebrated of which are the Via Appia, the Via Latina, and the Via Valeria. The former of these bounds the maritime portion of Latium, as far as Sinuessa, the latter extends along Sabina as far as the Marsi, whilst between these is the Via Latina, which falls in with the Via Appia near to Casilinum,¹ a city distant from Capua² 19 stadia. The Via Latina commences from the Via Appia, branching from it towards the left, near to Rome. It passes over the Tusculan mountain, between the city of Tusculum³ and Mount Albanus; it then descends to the little city of Algidum,⁴ and the Pictæ tavern; afterwards the Via Lavicana joins it, which commences, like the Via Prænestina, from the Esquiline gate. This road, as well as the Esquiline plain, the Via Lavicana leaves on the left; it then proceeds a distance of 120 stadia, or more, when it approaches Lavicum, an ancient city now in ruins, situated on an eminence; this and Tusculum it leaves on the right, and terminates near to Pictæ in the Via Latina. This place is 210 stadia distant from Rome. Proceeding thence along the Via Latina there are noble residences, and the cities Ferentinum,⁵ Frusino,⁶ by which the river Cosa flows, Fabrateria,⁷ by which flows the river Sacco,⁸ Aquinum,⁹ a large city, by which flows the great river Melfa,¹⁰ Interamnium, situated at the confluence of two rivers, the Garigliano and another, Casinum, also an important city, and the last of those belonging to Latium. For Teanum, called Sidicinum,¹¹ which lies next in order, shows by its name that it belongs to the nation of the Sidicini. These people are Osci, a surviving nation of the Campani, so that this city, which is the largest of those situated upon the Via Latina, may be said to be Campanian; as well as that of Cales,¹² another considerable city which lies beyond, and is contiguous to Casilinum.¹³
