Ala Gallorum Sebosiana

The Ala Gallorum Sebosiana [Postumiana] ( German Ala der Gauls des Sebosus [the Postumian] ) was a Roman auxiliary unit . It is evidenced by military diplomas and inscriptions. In the inscriptions and brick stamps it is referred to as Ala Sebosiana or Ala Sebusiana .

Name components

Gallorum : the Gaul . The soldiers of the Ala were recruited from the various tribes of the Gauls when the unit was formed.

Sebosiana : of Sebosus. The Gauls' cavalry units were often named after one of their first commanders. Statius Sebosus is named here as the namesake .

Postumiana : the Postumian. An honorary title that refers to Postumus (260–269). The addition appears in the inscription (RIB 605).

Since there is no reference to the addition of milliaria (1000 men) to the name , the unit was an Ala quingenaria . The nominal strength of the Ala was 480 men, consisting of 16 towers with 30 riders each.

history

The Ala was stationed in the provinces of Germania and Britannia (in that order). It is listed on military diplomas for the years 103 to 178 AD. Tacitus mentions the unit in his Historiae (Book III, Chapter 6) as Ala Sebosiana .

The unit was initially stationed in the province of Germania in the 1st century . At an unspecified time, the Ala was relocated to the province of Britannia , where it is first evidenced by a diploma dated 103. The diploma lists the Ala as part of the troops (see Roman Forces in Britannia ) that were stationed in the province. Other diplomas, dated 122 to 178, prove unity in the same province.

The last evidence of the Ala is based on the inscription (RIB 605) which is dated to 262/266.
