This plan of Petra's Civic Center is based on a map published in McKenzie's Architecture of Petra (McKenzie 1990:map 8). In this plan, however, I color-coded the features to illustrate the chronological development of the city and its expansion eastward as I understand and interpret the current evidence. This phasing indicates the initial construction of the monuments only and does not include subsequent renovations which would require a much more complex plan than can be presented here. A more thorough account of the phasing of Petra's civic center during the Nabataean and Roman periods is included in my dissertation (Bedal 2000).
It should be noted that the Temple of the Winged Lions has been dated by its excavator to the early 1st c. CE ( = Nabataean II-green) based on the discovery of an inscription dated 28 CE. However, the inscription only indicates the latest possible date for the construction of the temple. I choose to include the Temple of the Winged Lions in the earlier phase (purple) because I believe that its orientation, which is in line with the Qasr el-Bint and Temenos area, is significant to its dating. However, should this monument prove to be dated to 28 CE, its assignment to the Nabataean II phase would not change the concept of eastward expansion.
