BAIANUS SINUS, a bay so called from Bais, (Suetonius); Portus Baiarum, (Pliny); which was enlarged by Augustus, by giving entrance to the sea into the Lacus Luerinus, and Avernus, ordering it to be called Portus Julius apud Bais, (Suetonius). We also read Baianus Lacus in Tacitus, which some interpret the Luerinus. The modern name is Golfo di Pozzano. From the highest point that forms the bay, a large castle commands the road, where foreign ships of war usually ride at anchor, the harbour of Naples not being spacious enough for the reception of a fleet: here they enjoy good shelter, watering, and victualing; but in summer risk the health of their crews, on account of the unwholesomeness of the air.
