Limes Arabicus

The Limes Arabicus was a desert frontier of the Roman Empire, mostly in the province of Arabia Petraea. It ran northeast from the Gulf of Aqaba for about 1,500 kilometers (930 mi) at its greatest extent, reaching Northern Syria and forming part of the wider Roman limes system. It had several forts and watchtowers.

The reason of this defensive "Limes" was to protect the Roman province of Arabia from attacks of the barbarian tribes of the Arabian desert.[1] The main purpose of the Limes Arabicus is disputed; it may have been used both to defend from Saracen raids and to protect the commercial lines from desert-based robbers.

Next to the Limes Arabicus Trajan built a major road, the Via Nova Traiana, from Bostra to Aila on the Red Sea, a distance of 267 miles/430 kilometres. Built between 111 and 114 AD, its primary purpose may have been to provide efficient transportation for troop movements and government officials as well as facilitating and protecting trade caravans emerging from the Arabian peninsula. It was completed under Hadrian.[2]

Fortification[edit]

During the Severan dynasty (AD 193-235), the Romans strengthened their defences on the Arabian frontier. They constructed several forts at the northwest end of the Wadi Sirhan, and improved the roads. One important fort was Qasr Azraq.

A larger fort is Humeima (ancient Auara), which was built in the late second century and is therefore the earliest known Roman fort on the Arabian frontier. It was located on the Via Nova between Petra (44 km, 27 mi., to the north) and Aila (55 km, 34 mi., to the south) in the Hisma, Jordan's southern desert. The fortress was built at the north edge of a major Nabataean, Roman, and Byzantine community. It was probably abandoned in the fourth century. It is about 3 ha. (more than 7 acres) in size and rectangular in shape. It had four gates, one in the middle of each wall. It had projecting rectangular interval and corner towers. It could have housed a standard auxiliary unit of 500 men. [3]

Around 300 AD, Diocletian partitioned the old province of Arabia by transferring the southern region to the province of Palaestina. Later in the 4th century, Palaestina was made into three provinces, and the southern one was eventually called Palaestina Tertia. Each province was administered by a praeses with civil authority and a dux with military authority.

Diocletian engaged in a major military expansion in the region, building a number of castella, watchtowers, and fortresses along the fringe of the desert just east of the Via Nova. This line of defence extended from south of Damascus to Wadi al-Hasa. The region from Wadi Mujib to Wadi al-Hasa contained four castella and a legionary camp. The frontier south of Wadi al-Hasa, which extended to the Red Sea at Aila (Aqaba), may have been called the Limes Palaestina.[4] In this region, ten castella and a legionary camp have been identified. The term may have referred to a series of fortifications and roads in the northern Negev, running from Rafah on the Mediterranean to the Dead Sea,[5] or to the region under the military control of the dux Palaestinae, the military governor of the Palaestinian provinces.[6]

Personnel[edit]

There were castra every 100 kilometres (62 mi) with the purpose to create a line of protection and control:[7] in the south there was the legionary fortress at Adrou (Udruh), just east of Petra. It probably housed the Legio VI Ferrata, which was moved from Lajjun (Israel) by Diocletian.[8] It is similar to Betthorus (el-Lejjun in the plain of Moab, south of Wadi Mujib) in size (12 acres (4.9 ha)) and design. Alistair Killick, who excavated the site, dates it to the early 2nd century, but Parker suggests a date in the late 3rd or early 4th century.

A legionary camp may have also existed at Aila (modern Aqaba), which has been excavated by Parker since 1994. The city was located at the north end of the Gulf of Aqaba where it was a centre of sea traffic. Several land routes also intersected here. Legio X Fretensis, originally stationed in Jerusalem, was transferred here to the terminus of the Via Nova. So far, a stone curtain wall and projecting tower have been identified, but it is uncertain whether they were part of the city wall of Aila or the fortress. The evidence suggests the fort was constructed in the late 4th or early 5th century.

Troops were progressively withdrawn from the Limes Arabicus in the first half of the 6th century and replaced with native Arab foederati, chiefly the Ghassanids.[9] After the Arab conquest the Limes Arabicus was left to disappear, but some fortifications were used and reinforced in the following centuries.
