Kleiner, Diana E. E., HSAR 252 Roman Architecture,Spring 2009. Yale Open Course Ware: History of Art, Accessed 3/10/14, http://oyc.yale.edu/history-art/hsar-252/lecture-16 License: Creative Commons BY-NC-SA Professor Kleiner focuses on Ostia, the port of Rome, characterized by its multi-storied residential buildings and its widespread use of brick-faced concrete. She begins with the city's public face--the Forum, Capitolium, Theater, and Piazzale delle Corporazioni. The Piazzale, set behind the Theater, was the location of various shipping companies with black-and-white mosaics advertising their business. Professor Kleiner examines the Baths of Neptune and the Insula of Diana, a brick apartment building with four floors that housed a number of Ostia's working families.
