Note 285 — Chapter XIII · THE AFRICAN PROVINCES.

If the praefect of a cohort doing garrison duty in Numidia held the command at the same time over six Gaetulian tribes (nationes, C. I. L. v. 5267), men that were natives of Mauretania were employed as irregulars in the neighbouring province. Irregular Mauretanian horsemen frequently occur, especially in the later imperial period. Lusius Quietus under Trajan, a Moor and leader of a Moorish troop (Dio lxviii. 32), no Λίβυς ἐκ τῆς ὑπηκόου Λιβύης, ἀλλ' ἐξ ἀδόξου καὶ ἀπῳκισμένης ἐσχατιᾶς (Themistius, Or. xvi p. 250 Dind.), was without doubt a Gaetulian sheikh, who served with his followers in the Roman army. That his home was formally independent of the empire, is not affirmed in the words of Themistius; the “subject-territory” is that with Roman organisation, the ἐσχατιά its border inhabited by dependent tribes.
