Leading-edge Pompeii researcher Matthew Selheimer chaired a symposium at the Archaeological Institute of America’s annual meeting, (the AIA) talking about the fountains, roads and intersections of the world’s most famous archaeological site.
Three engaging pieces of research were presented about Pompeii in the debate facilitated by Dr. Selheimer, but extra colour was added to the session by additionally featuring a study of the social costs and benefits of building work in a city context, which whilst officially focussed on Rome, the insights into the stressful life whilst new buildings were being installed were just as relevant to Pompeii too.

1.The paper by Matthew Notarian highlighted the function of all the fountains in Pompeii – there was a dense grid of these on street corners all fed by fresh water from the Serino Aqueduct and comparable to the ‘nasoni’ aqueducts on street corners across Rome.
There were more than 2000 doorways in Pompeii and Notarian has calculated least-cost street routes from every doorway to the nearest fountain by factoring the effect of Pompeii’s natural topography on pace. One surprise in Notarian’s paper was his assumption that women would have performed most of the carrying of water in ancient Pompeii.
The study of fountains is not so straightforward: “They are built of different materials, different sizes, and different arrangement of stones, and even different types (basin, pillar, etc.) – says professor Notarian – It is open question whether these differences reflect different chronological phases of the city’s water supply, different supplies of building materials, different benefactors (public, private), etc. I proposed in my paper that the varying sizes may reflect an organized plan to install larger basins in regions of the city with a higher concentration of individual private dwellings, although some fountains were over or under utilized nonetheless”.
Notarian’s digital elevation models and his map of the fountain / door street network which includes all the fountains used for public water in the study pose new questions about water supply – particularly to the highest parts of the city.

2. Selheimer’s presentation concernedthe nature of two crossroads of Pompeii, both adjacent to baths-complexes, one in the western portion of the walled city north of the forum, and one towards the centre where the street widens to form a ‘piazza-like area’ in the E-W road which is higher than the N-S road, the later of which features a public fountain adjacent to a water tower. Selheimer analysed both of these cross-roads concentrating on a ‘streetview’ rather than the ‘plan view’ of each crossroads and showed an in-depth knowledge of the urban structure of Pompeii and intuitive understanding of how its topography would fit in with the lives of the ancient inhabitants.
One question remained unanswered: Selheimer was unaware of any evidence to indicate how traffic was organised in Pompeii’s ancient streets. The streets were very narrow, and damage from cart wheels indicates that carts would have occupied the entire width of one of the city streets. For completeness, his research needs to help us understand better how they were regulated: whether the directionality of traffic flow along these streets was regulated by traffic policemen or whether each street had a set direction of flow at a particular time of day, for example
