Augusta (title) in the context of "Autokrator"

The Severan dynasty, sometimes called the Septimian dynasty, ruled the Roman Empire between 193 and 235.It was founded by the emperor Septimius Severus (r. 193–211) and Julia Domna, his wife, when Septimius emerged victorious from civil war of 193 - 197, which began with the Year of the Five Emperors.Their two sons, Caracalla (r. 192–217) and Geta (r. 211), ruled briefly after the death of Septimius.In 217 - 218 there was a short interruption of dynasty's control over the empire by reigns of Macrinus (r. 217–218) and his son Diadumenian (r. 218) before Julia Domna's relatives assumed power by raising her two grandnephews, Elagabalus (r. 218–222) and Severus Alexander (r. 222–235), in succession to the imperial office.

The dynasty's women, Julia Domna, the mother of Caracalla and Geta, and her sister, Julia Maesa, the mother of Julia Soaemias and Julia Mamaea, mothers of Elagabalus and Severus Alexander respectively, were all powerful augustae.They were also instrumental in securing imperial positions for their male relatives.

Valentinian III (Latin: Placidus Valentinianus; 2 July 419 – 16 March 455) was Roman emperor in the West from 425 to 455. Starting in childhood, his reign over the Roman Empire was one of the longest, but was dominated by civil wars among powerful generals and the barbarian invasions. He was the youngest sole emperor in the Western Roman Empire (aged 6).

He was the son of Galla Placidia and Constantius III, and as the great-grandson of Valentinian I (r. 364–375) he was the last emperor of the Valentinianic dynasty. As a grandson of Theodosius I (r. 379–395), Valentinian was also a member of the Theodosian dynasty, to which his wife, Licinia Eudoxia, also belonged. A year before assuming the rank of augustus, Valentinian was given the imperial rank of caesar by his half-cousin and co-emperor Theodosius II (r. 402–450). The augusta Galla Placidia had great influence during her son's rule, as did the military commander Flavius Aetius, who defended the western empire against Germanic and Hunnic invasions. Attila the Hun repeatedly menaced Valentinian's domains, being repulsed by a coalition under Aetius's leadership at the Battle of the Catalaunian Plains and calling off a subsequent invasion after negotiations led by Pope Leo I.

The Severan Tondo or Berlin Tondo from c. 200 AD is one of the few preserved examples of panel painting from classical antiquity, depicting the first two generations of the imperial Severan dynasty, whose members ruled the Roman Empire in the late 2nd and early 3rd centuries. It depicts the Roman emperor Septimius Severus (r. 193–211) with his wife, the augusta Julia Domna, and their two sons and co-augusti Caracalla (r. 198–217) and Geta (r. 209–211). The face of one of the two brothers has been deliberately erased, very likely as part of damnatio memoriae.

On the viewer's right is Septimius Severus, and to the left Julia Domna. In front of them are the boys Caracalla and Geta. All wear jeweled gold wreaths and imperial insignia, some details of which have been lost. The dating of the piece has caused some debate among scholars, with the final consensus being c. 200 AD. The tondo has many stylistic connections to Fayum Mummy portraiture including materials and artistic elements, and its production has been located in the Fayum district of Egypt during this period. Later on the tondo re-emerged from the antiquities trade; the provenance is unknown before entering the Antikensammlung Berlin (inventory number 31329) in the 20th century. It is now in the Altes Museum.
