A number of questions are currently under discussion, both within and outside the team.
1) The stages of the city's development: what was the city in the 120 years or so of its existence before it was remodelled by Eucratides? The name it bore at that time is not known (a toponym transmitted by Ptolemy, Oskobara, "the high enclosure", may have referred only to a pre-existing Achaemenid fort on the citadel). The recent resumption of the study of ceramics from the various building sites suggests that the founders' grand design took a long time to materialize, with the residential quarter in the southern part only taking shape at the very end of the 3rdcentury [1]. Moreover, even at the end of the period, the population of this colonial quarter, comprising some forty residences, cannot have exceeded a few hundred inhabitants, including domestic staff. The contrast with the theater's capacity is striking.
It seems that these questions can only be answered if we leave the ramparts. The plain immediately to the north was also receiving settlers; the additional canal dug at great expense during the Greek period allowed only a marginal gain in cultivated areas, indicative of a demographic overload. The same observations were made in the more distant plains, which must also have been part of the city's chôra. On the other hand, a fortified round town of respectable size (around 30 ha plus a part that disappeared into the river), occupied before, during and after the existence of Aï Khanoum, stood 1.5 km to the north (the same distance as between the two Nisa). The space in between was itself quite densely occupied, and the first belt beyond the Aï Khanoum rampart could even be defined as an "urban zone" (H.-P. Francfort) featuring buildings of a high social standing: large residences, a temple and mausoleums. We are led to believe that, despite its imposing appearance, the northern rampart of Aï Khanoum did not materialize the limit of the urban organism. Could it be that the majority of the first settlers lived in the city they found, the "Round City"?
