Sebatum

In his Corpus Inscriptionum Latinarum V,1, page 1838, edited 1877, Theodor Mommsen discusses  a slab found in Zuglio in 1838 with the following inscription:

C . BAEBIO . P . F CLA ATTICO

A translated excerpt from the Latin article:
... There exists a connection between the town of Saevatum and the Sevaces, of whom Ptolemy 2, 13, 2, reports they had their dwellings in the north, in the Western Noricum, and hence it is, as Henzenus had already supposed following the Itinerarium Antonini p.280 … the town of  St Lorenzen in the Pustertal.
The Laiances are hitherto unidentified, unless they are the people indicated by Ptolemy together with the Saevates as Alaunoi, the latter term however possibly also being only a transmogrification of Laiangkoi.

The Administrative District of Sebatum

Since its integration into the Roman Empire of the Province of Noricum, to which Sebatum belonged, the capital of the it was Virunum in the Zollfeld next to the Magdalensberg, 14 km from Klagenfurt in Carinthia.

After the reformation of the state implemented by Diocletian in A.D. 284 first and the reorganisation of the army effected by the Emperor Constantine, Noricum was subdivided into two distinct areas: the so called Bank Noricum south of the banks of the Danube and  concerning Sebatum on the one hand, and Noricum Mediterraneum with its first capital Virunum in the 5^th c. A.D. then replaced by Teurnia, today called St Peter in Holz, in Carinthia on the other.  

During this whole period Sebatum was subject to the Municipium Claudium Aguntum, which had been istituted in the 1^st c. A.D. and was the district capital of the Ager Aguntinus. The next neighbouring centres of administration were Tridentum, today Trento, and the above mentioned Teurnia.  

In this geopolitical constellation Sebatum detained a certain importance as frontier town to the Provincia Raetia Secunda which lay to the west. The precise borderline can’t be determined anymore but will have to be looked for between the Mühlbach Defile and the Eisack Valley on the one side and between the Kunters Road in the south and the Mittewald Defile in the north on the other side. At any rate in documents from the end of the 10^st c. A.D. there is evidence that at this time the Bayuvars which had in the meantime moved in called that part of the Eisack Valley Norica Vallis or Nurihtal.
