Majores

The Roman emperor Trajan established a frontier in the south by encircling the Aurès and Nemencha mountains and building a line of forts from Vescera (modern Biskra ) to Ad Majores (Hennchir Besseriani, southeast of Biskra).

These four dignitaries, occupying the four corner stalls in the choir, are called in many of the statutes the quatuor majores personae of the church.
