I have been trying to find to find out a bit about Giambattista Nolli, who was responsible for the greatest street maps of Rome, which he began work on in 1736 and published in 1748 as the Pianta Grande di Roma, at almost exactly the same time that John Roque was working on the equivalent street map of London, published in 1747. Nolli is a minor cult figure amongst architects in clearly showing the relationship between streets, public spaces and public buildings (indeed, the reason I have been trying to find out about him is that one of our architectural advisers did a Nolli of Mayfair). Not much seems to be known about him. He was born in 1701, moved to Rome, published the map at the request of Pope Benedict XIV and with the help of Piranesi, and died in 1751, not long after the map was published, his life work. The point of the map is that the city is an organism, in which each individual part contributes to the while; and that the city is experienced through walking through the streets, rather than through looking at individual buildings. You can see why I am interested in him.
