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-18 License: Creative Commons BY-NC-SA Professor Kleiner discusses two Roman cities in North Africa: Timgad and Leptis Magna. Timgad was created as an entirely new colony for Roman army veterans by Trajan in A.D. 100, and designed all at once as an ideal castrum plan. Leptis Magna, conversely, grew more gradually from its Carthaginian roots, experiencing significant Roman development under Augustus and Hadrian. Septimius Severus, the first Roman emperor from North Africa, was born at Leptis and his hometown was renovated in connection with his historic visit to the city.
