interesting map shows Campania --the area of the Bay of Naples-- as
it appeared in Roman times. Note the main Roman roads coming from Rome
and the north. Naples, of course, was important, BUT not as important
as Pozzuoli (identfied as "Puteoli" on
the map (with the old Greek name of "Dicaearchia" below it in parentheses).
There are, in fact, separate main roads leading to Cuma
on the coast and Puteoli, indicating the importance of this area as
the port for the Western Imperial Fleet.
You may wish to compare this map to the one of the Campiflegrei by clicking here. There you will see a graphic display
showing the area in more detail.
