Wargla, known to medieval Arab geographers as Wardjlan or Warklan, was one of the most important eastern oases of the northern Sahara. The excerpt gives no secure account of its origins, but suggests that a village may have existed there during the later Byzantine period. That settlement may have stood on a caravan route connecting Numidia with the Hoggar and perhaps the Niger Bend.

The name Wargla is tentatively connected with the Moorish tribe called the Urceliani by Corippus in the sixth century. The passage proposes that people belonging to this group may have built dwellings in the oasis before the Muslim invasion. It also records that several substantial towns already existed there when the first Arabs arrived in the Maghrib around the middle of the seventh century.

V. Largeau counted eleven towns or villages in the oasis at that time, with ruins still visible. Wargla therefore appears not merely as an isolated watering place but as a settlement cluster embedded in a wider Saharan landscape. Its position connected it with Wadi Righ, Suf, southern Tunisia, the central Sahara, and routes leading toward the Niger Bend.
