Archaeology of Oman
While traditional Oman also includes the present-day United Arab Emirates, its prehistoric remains differ in some respects from the more specifically defined 'Oman proper' which corresponds roughly with the present-day central provinces of the Sultanate. The Oman Peninsula is more specific which juts into the Gulf of Hormuz. Archaeologically speaking, differences grow between the area of the present-day U.A.E. and the Sultanate particularly toward the end of the Early Iron Age. Archaeology is conditioned locally by the geographical situation. The amount of moisture dictates the amount and place of agriculture and population that are sustainable. A variety of subsistence strategies exploit the available resources. Since archaeological field work began in the Sultanate in the early 1970s, numerous teams have worked in the Sultanate.
Different ages are reflected in typological assemblages, Old Stone Age, New Stone Age, Copper Age, Bronze Age, Early Iron Age, Late Iron Age, that is Samad Period, so-called late pre-Islamic culture and the Age of Islam. What is referred to as a period is inferred from a regularly recurring assemblages of artefacts. Some specialists equate periods with cultures. The names of the ages are conventional and are difficult to fix in terms of absolute years. Aside from this the development is highly regional. The archaeological assemblages of the South Province Dhofar differ completely from those of the central part of the country. A key barometer of industrial activity is the amount of copper production, as known from smelting refuse (slag) and metallic artefacts.
Except for the Islamic period, what they all share is that they are known primarily from cemeteries, tombs and grave goods. The absolute dates for the different periods are still under study and it is difficult to assign years to the Late Iron Age of central and southern Oman. Even major monuments have been dated variously, spanning millennia. The meanings of major concepts such as Arab are controversial.
Old Stone Age: Looking to archaeogenetic research, the emerging picture indicates a major dispersal of our species out of Africa between 100 and 50 thousand years ago. Despite the numerous studies proposing early human population expansions from Africa into Arabia during the Late Pleistocene, no archaeological sites have yet been discovered in Arabia that resemble a specific African industry, which would indicate demographic exchange across the Red Sea. Known primarily from survey finds. Lithic findspots near Ra's al-Jins. Main sites include Saiwan-Ghunaim in the Barr al-Hikman.
New Stone Age: The first agricultural settlements. Known from a variety of sites, most of which lie on the coast. The most characteristic feature is the domestication of plants and animals and a shift toward settled life.
Copper Age, Hafit: Known originally from a cemetery site on the Jebel Hafit in the United Arab Emirates (UAE). Like the following Bronze Age periods, sites with characteristic finds are distributed over the UAE and Sultanate. Typically burial cairns lie on top of hill crests. Copies and pottery imports from southern Mesopotamia occur. Such finds have been documented on the eastern coast of the Sultanate near Ra's al-Hadd, especially HD-6 and Ra's al-Jinz. Diagnostic pottery of Jemdet Nasr type has survived in some tombs. The smelting of oxidic copper ores begins, as perhaps at al-Batina. Such ores would leave little slag and the process did not require special conditions. Already at this time there is textual evidence from Sumer for international trade in copper and other commodities, probably from Oman.
Bronze Age 2500 - 1900 BC: The Umm an-Nar and Wadi Suq Periods (1900 - 1300 BC). Examples may be found at numerous funerary sites, for example on the island Umm an-Nar and in the Wadi Suq. Typical of this period are wheel-turned painted vessels which distinguish these two periods. During the Bronze age, metal production increased considerably in relation to that of the preceding Hafit Period, with several specimens of plano-convex copper ingots weighing 1–2kg found. Tower tombs, such as those at Shir ( ), can only be approximately dated, and may date to the Hafit or Umm an-Nar Periods. During the Umm an-Nar Period, large communal, free-standing tombs contain numerous interments. Other tombs are smaller and may contain one or a few interments. Settlement remains have been excavated at Ra's al-Jinz (RJ-2).
Early Iron Age
1300 - 300 BC: Known from different cemetery and copper producing sites including the fort on the Jebel Radhania, Lizq. This period is known from some 142 archeological sites (or 161 depending on how one counts) located in the eastern part of the United Arab Emirates as well as the Central and northern part of the Sultanate of Oman. Usually hand-made, hard-fired pottery. The chronology and its nomenclature are controversial. The pottery from the Lizq fort is most similar to that from the latest Early Iron Age sites at al-Moyassar and Samad al-Shan. In terms of pottery chronology, its beginnings there are obscure. The dead are interred in existing subterranean tombs or in hut-like free-standing ones. Such tombs have poor chances of survival and as a ready source of building materials have rapidly disappeared since 1980. Copper production reaches a peak at this time which will only be surpassed in around the 9th century AD. The reason is that the technology to roast the more abundant sulphidic copper ore was developed. A hoard of copper alloy artefact at ʿIbri/Selme gives a fair idea of the production at this time. In 2012 a copper and iron metal-working workshop came to light first reported incorrectly as at 'al-Saffah', 'as-Safa' (السفة), actually al-Ṣafāʾ (الصفا) after a site some 40 km to the south-west []. In reality this site is known as ʿUqdat al-Bakrah (عقدة البكرة). It yielded to date nearly 700 metallic artefacts. The introduction of the falaj for irrigation coincides with the rapid growth of date as a main crop. The chronology for this age resembles but also differs from the better known one of the present-day U.A.E. During this Iron Age paradoxically in Oman iron artefacts have not yet been recovered. In neighbouring Iran after 1200 BC iron weapons are characteristic. Pre-Arabic place-names such as Izki, ṣuḥar and ʿIbri probably represent the bare remnants of the language and speakers of this and the next age.
Late Iron Age
Evidence exists for the Samad Late Iron Age from 150 BC to 300 AD, dated by means of a few outside comparisons. This assemblage is known from 74 archaeological sites in 29 localities and four suspected ones. Evidence for a transition from the EIA is rare in Central Oman and the situation is clearest at the multi-period site complex at al-Maysar (al-Moyassar): falaj waters sites from the EIA, LIA and medieval periods survive to this day . Over the centuries the water table dropped, so that the floor had to be lowered to the height of the water table. Samad LIA sites scatter over an estimated 80,000 km2. Defective radiocarbon dates found no acceptance. Samad al-Shan and smaller sites, such as al-Akhdar, al-Amqat and al-Bustan, are type-sites for this non-writing population, with mostly hand-made pottery, copper alloy and iron artefacts. Reoccurring pottery wares and shapes, small finds as well as a few grave structure types define the Samad Late Iron Age assemblage. Typically, individual stone-built graves are sunk into the earth in the plain. Classical Samad graves have a small wall on the roof near one end perpendicular to the long axis. Few fragmentary settlements (al-Nejed, Mahaliya, Qaryat al-Saiḥ in Wadi Maḥram, Samad S1, S7, ʿUmq al-Rabaḫ) have been documented. No coins were struck locally, and to date only a single example has turned up in a context together with Samad Late Iron Age pottery. Some glazed pottery imports derive from the north. One class of pottery, balsamaria are wheel-turned and also are common in the late Pre-Islamic so-called PIR graves also in the U.A.E.. Approximately 3/4 of the Late Iron Age find inventories in Central Oman finds are attributable to the Samad assemblage, fewer to the so-called [préislamique récente], and a few cannot be attributed to a definable find assemblage. Certain towns in Oman perhaps were dominated politically and militarily by Parthian and later Sasanian invaders from Iran. But for logistical reasons it was possible to occupy only a few sites. The bulk of the population were mixed Semitic speakers. Persian presence is inferred by a few place-names near or on the coast (e.g. Rustaq) and personal names in Izki. Perhaps the bulk of the Early Iron Age population of central Oman spoke so-called Modern South Arabian languages. From ±500 BC to ±500 AD or later, waves of migratory tribes from South and Central Arabia settle in Oman and Iran as we know from different sources. The Azd tribes of course are far larger and more diverse than the area of the Samad Late Iron Age sites. These tribes brought the Old South Arabian, later Classical Arabic with them as far east as Khorasan in Iran. It is assumed that Arabic arrived with Arabs and Islam in the 7th century CE, first to the centres. There is a radical decline in population as compared to the preceding period. Evident is a loss of copper producing technology. The occurrence in Arabia and the Red Sea littoral of ribbed amphorae manufactured in Aqaba/Ayla evidently in order to transport wine, shows the area just north of Aqaba to habe been a fruitful agricultural area from 400 up to possibly 1000. On the other hand, D. Fleitmann has studied speliotherms from al-Hootha cave in central Oman and has gathered information for a series of megadroughts especially around 530. These may have afflicted the entire Peninsula.
Recent Pre-Islamic Period: Known from different sites in the Sultanate, for example Amlah, al-Fuwaidah. Such sites are largely contemporary with Late Iron Age of Samad in Central Oman, especially in the Sharqiyah. In the U.A.E. such show evidence of writing such as on coins. Regarding the relative chronology of the two there is considerable consensus. However, a difficulty in order to build a chronology lies in the lack of clear artefactual parallels between the Samad assemblage and that of these sites. At the partially excavated cemetery site of al-Fuwaidah the artefacts, especially pottery and metalwork, are more similar to contemporary ones from the U.A.E. than to those of Samad.
Iron Age in Dhofar
Late Iron Age in Dhofar: Survey and a few excavations shed light on the archaeology of the South Province of the Sultanate. The largest and best-known site is Khor Rori - a trading fort established by the Hadhramite kingdom in the 3rd century BC. While this site shows a mixture of artefacts, many of which are of Old South Arabian type, the surrounding countryside reveals a melange of different kinds of artefacts. Khor Rori owes its existence to the trading of aromatics, in particular frankincense. The type of sherd depicted was for many years considered to be Late Iron Age. Recent research re-dates to the medieval period.
Very little archaeological evidence from the early Islamic Age exists. The earliest building structures which survive date to medieval times. With the coming of Islam and the diaspora of Arabian tribes, the Arabic language takes hold in Oman. Copper production reaches a record high to judge from the amount of slag which has survived. With 100,000 tons of slag, Lasail is the largest smelting site in Oman.
