Due to the similarity of the hairdressing fashion on female head with the portraits of Domitia Longina written by J. Inan and E. A. Rosenbaum who have important studies about Roman imperial portrait art, Flavian Dynasty period was proposed directly. In the study in 1979, no typological distinction was made among the portraits of Domitia Longina and Domitia Longina portraits were limited to the Flavian Dynasty. Hairdressing fashion in the form of a spongy mass of hair, which is very important in identifying and dating this period, also looks like a wreath-like hair mass in Istanbul piece. This hair style is not similar to the hairdressing fashion of the portraits of Iulia Titi and Domitia Longina during the Flavian Dynasty. It is similar to the portraits of Domitia Longina in IIIrd type who was honoured after the Flavian Dynasty and of whom portraits were made with new hair fashion. Although this new hair fashion, which is dated to Nerva - Early Traianus period, is reminiscent of the Flavian Dynasty in essence, this hairdressing fashion in which the hair tresses are portraited more exaggerated should be dated after the Flavian Dynasty.
