The museum contains one of the portraits of Trajan of which only the head remains. The head has massive proportions that relate, according to specialists, to several types of the aging emperor. Some think it is a posthumous portrait erected by local authorities to thank the founder of the colony
We also have to award at the time of Trajane a grey marble triumphant procession. There is there only a bottom. It represents, in natural greatness, a horse, the driver of a tank and a captive to the excessive proportions was based and chained.
If the attribution of a bust to Emperor Hadrian is not disputed, we find it difficult to identify a worn out female portrait found during the dredging of the harbor in 1898. Some attribute it to Marciane or Matidia, sister and niece of Trajan; others, like A. Carandini, attribute it to Sabine, Hadrian’s wife. The kinship between these women and the similarity of their portraits, particularly as regards the details of hairstyle, make their identification difficult. However, we should probably opt for Sabine whose images were widely disseminated in Africa.
The imperial family is still represented by a portrait attributed to Fulvia Plautilla, wife of Emperor Caracalla (211-217), whose physical characteristics can be seen on monetary emission from the early 3rd century.
