With continuing interest in DH work and Urban Studies, I’ve just been referred to this interesting project:
Views of Rome is the online home of the 1773 edition of Pirro Ligorio’s Anteiquae Urbis Imago (Image of the Ancient City) held at Emory University. Originally published in 1561, the Imago is a cartographic reconstruction of fourth-century AD Rome. A high-resolution scan of the map exists as an interactive digital tool for use by students in the classroom and by members of the general public.
