|Three roman forts, Praesidium, Thamara and Moa have been placed by the mosaicist in the valley of Arabah to the south of the Dead Sea. These forts guarded the roads which joined the edomite territory to the palestinian coast crossing the Negev which is graphically represented by three isolated mountains.
The first caravan stop was the city of Mampsis identified by the ruins of Kurnub. A largish quadrangular vignette is dedicated to Beersheba now Berossaba with an added biblical geographic annotation; To which arrived the borders of Judea to the south, starting from Dan near Paneas, which borders it from the north.
The cited localities in the Negev, the territory of the tribe of Simeon are; Arad, whence the Aradites, Gerara once the royal city of the Philistines and border of the Canaanites from the south, where the Saltus Gerariticus is found, Iethor which is also Iethera, Elusa which was the episcopal seat of the Negev, Photis, Orda and Asemona, city by the desert the boundary between Egypt and the crossing towards the sea.
