Belgian archaeological expedition in the U.A.E. reveals the existence of
an Ancient Kingdom of Oman.
team directed by Dr Bruno Overlaet from the Royal
Museums of Art and History in Brussels, and working in close collaboration
with Sharjah's Department of Antiquities made
a discovery of major historical importance at the archaeological site of Mleiha
in the central region of the U.A.E. The find was made on 17 December 2015, the
last day of the team's fieldwork. The discovery was revealed to the press by
the Ruler of Sharjah, His Highness Dr Sheikh Sultan Bin Muhammed Al Qasimi on
28 Januari 2016.
tomb measuring approximately 5.20 by 5.20 meter is under excavation, work on it
is planned to resume in the fall of 2016. A square building of lime-bricks once
stood on top of two underground burial chambers. These chambers, which once
contained the deceased and the grave goods, had walls constructed with large
boulders. The passage between the rooms was blocked with bricks and a large monumental
inscription that had fallen down from the upper structure.
bi-lingual inscription is written in Aramaic and Ancient South Arabian. The
exceptionally well preserved text reveals the identity and the family lineage of
the deceased, as well as the date when the monument was built. The central
panel of the stone is written in Ancient South Arabian. It states that the tomb
was build by the son of a certain ʿAmīd, who was in the service of the king of Oman.
An Aramaic inscription is placed on the rim around the central panel. It gives
the date when the monument was erected, in the year 90 or 96 of the Seleucid
era, the equivalent of 222/221 or 216/215 BCE.
inscription provides the oldest mention of the name Oman and
proves that a kingdom of Oman already existed in the late 3rd
century BC. The local Abiel dynasty,
known from its coins minted at Mleiha, can in all probability be associated with
this title of "King of Oman”. Their kingdom was apparently centered around
Mleiha and probably consisted of the territory of the U.A.E. and the Northern
parts of the Sultanate of Oman. Up to now, the oldest mentioning of the name was
in Classical sources from the 1nd century CE where Omana refers to a harbour on the Oman peninsula.
This Omana in the Periplus
Maris Erythraei (Voyage around the Erythraean Sea) and in the Natural History by Plinius the Elder, is usually
associated with the coastal sites of either ed-Dur in Umm al-Qaiwain Emirate or
with Dibbah in Sharjah Emirate, both in the U.A.E. The identification of Mleiha
as the royal seat, suggests the Classical authors referred to a harbour that
served Mleiha, as the capital of the Oman Kingdom.
this stage, only the upper part of the burial chambers has been excavated. The excavation
will be resumed in the Fall of 2016.

6th archaeological campaign
at Mleiha, Sharjah (UAE)
The Royal Museums of Art and History,
A Belgian team works at Mleiha
since 2009. The 2014 campaign (20/11-18/12/2014) was mainly a study campaign on
the architectural remains, finds and ceramics that are kept in storage at the
site. The field activities were limited to surveying and to the continuation of
the excavation of two monumental tombs that had started the previous year. At
the same time, a drone for aerial photography was tested in various weather
conditions and environments. The 2014
expedition is supported by the Royal Museums, the FWO (Research Foundation - Flanders) and the IAP VII (Greater Mesopotamia: Reconstruction of its Environment and History) and works in
close collaboration with the Directorate of Antiquities of the Emirate of
Sharjah, headed by Dr. Sabah Jasim. The expedition is
directed by B. Overlaet (RMAH), members and collaborators of the 2014 team were
E. Haerinck (senior archaeologist), B. De Prez, P. Pincé and L. Van Goethem (archaeologists), H.
Steenbeke and M. Coppejans (architectural reconstructions) and Patrick Monsieur

During the first four years a
large surface with 7 monumental tombs and 4 more modest pit graves (zone P) was
excavated on the eastern fringes of the site (Fig. 2). In 2013 a ground
penetrating radar survey targeted its surroundings, extending the research area
eastwards up to the modern wadi. A series of tombs with monumental square
superstructures were revealed and the excavations documented the presence of
modest pit tombs between the clusters of monumental tombs (Fig. 2). The two
monumental tombs excavated in the 6th season are located on the low
mound Z. Both tombs were looted but still produced interesting finds such as
Rhodian amphora fragments, Mesopotamian glazed luxury vessels, various types of
gold beads and alabaster vessels from Yemen. All these point to a date in the
first half of the 2nd century BCE. They illustrate the importance and
the role of Mleiha on the Arabian trade routes and contribute important
elements for the chronology of the Oman peninsula.

Drones and aerial photography
Drones are ideal for
oblique overviews of excavations, vertical photography in view of mapping and
measuring and for more general surveying purposes. Drones can replace the use
of ladders and scaffolds and of kites or hot air/helium balloons on many digs. Professional drones
remain expensive and complex, however, and demand a skilled and well trained
pilot, often seconded by someone to operate the camera. In recent years, archaeologists
have therefore started to experiment with low budget recreational drones fitted
with lightweight cameras. Commonly reported problems of these early attempts were, however, a limited
flight time due to battery capacity, low quality photography and particularly
the inability to use the drone in anything but very light winds. The latest generation
of “consumer drones” have become increasingly user friendly and most of these
problems have been solved. We opted to experiment with a standard version of a
“DJI – Phantom 2” quadcopter mounted with a 12 MP camera on a damped 2D gimbal
for stability. The camera can be tilted in flight between a horizontal and
vertical position. An OSD or “On Screen Display” module streams the camera view
and technical and navigational data to a monitor on the remote controller. This
makes it ideal for low altitude aerial surveys in accordance with aeronautical
regulations (below 50 meter). The relatively small drone necessitates video
piloting (FPV, First-Person View) via the monitor when surveying larger areas
since it is impossible to keep track of it with the naked eye.

its transport case and mounted on a backpack.
The drone is kept “flight
ready” in a custom made protective transport case at the excavations and can be
made ready for flight within minutes. It can thus be used on the spot without
delaying any of the excavation activities.
During the 2014 expedition at Mleiha trials were made
in different environments and weather conditions. Flights were made above the
excavation field in the wadi plain and during surveys around the excavations
and on the nearby Jebel Fayah mountain ridge. Surveying flights above the wadi
during the early morning hours produced excellent shadow marks. Flights could
normally continue for several hours until stronger thermals started to develop
and “dust devils” started occurring. The general experience was very positive,
however. The drone could be flown in moderate to strong winds and performed
well in all conditions. With a maximum flight speed of 15m/s. (54 km/h.) it can
even counteract gusty winds.

marks of very low mounds with monumental tombs in area AV. The oblique view
emphasises the effect of the shadows.
Drone surveying in the mountains demands a somewhat
different approach. The drone was mounted on a backpack and used from various
points near the top of the Jebel Fayah (see fig. 1). Flights were made early in
the morning and halted once thermals, accelerated by their path across the
mountain, reached vertical velocities of more than 1m/second. In a mountainous
environment is keeping visual track of the drone essential in view of the
effect of local winds and turbulences on the flight path close to the relief. Turbulences
and thermal activities can be strong and develop rapidly. In general, these first trials on the Jebel
Fayah were all together positive. The technical equipment was effective and
allows covering large zones in limited timespans. During these first trials,
two structures - likely to be a musallahs or prayer area - were located and
documented. A general aerial survey of the mountain area could supply important
data to identify and protect local archaeological and historical heritage.

Belgian research at
Karon on the Oxus, Badakhshan - Tajikistan
Royal Museums of Art
and History & Royal Belgian Institute of Natural Sciences
Following a first visit to the site in October
2013 by B. Overlaet (RMAH) and the identification of quern stones near the site
as related to gold mining, an interdisciplinary team set out to investigate
this industrial activity and its impact on population and landscape. This
research wanted to complement the ongoing work at Karon by Tajik and Russian
expeditions. The Belgian team consisted of Prof. Dr. Bruno Overlaet, Laurence
Van Goethem (Royal Museums of Art & History, Brussels) and Rindert Janssens
(Royal Belgian Institute of Natural Sciences, Brussels). During this first
campaign at Karon (21/5 – 12/6/2014), a survey was made, an Islamic graveyard
was explored and geological and biological samples were collected for analysis.
Karon is situated on a mountain top along the
Panj river (Oxus) between Khalai Khumb and Kevron in the Darwaz region of
Tajikistan. Since 2012, the site is studied by Prof. Y. Yakubov (Academy of
Sciences, Tajikistan) and Dr. A. Nikitin (Hermitage Museum, Saint-Petersburg), who
were now joined by the Belgian team.
Karon: view towards the mountaintop palace, sunken
garden and pavilion.
Karon has a long history of human occupation, shown by the presence of
various types of tombs and isolated finds such as Kushan and Sogdian coins.
Yet, most of the constructions we see today date from the 15th-16th century, the
time of the Timurid and Shaybanid rulers. There is a huge walled area with a
palace, terrases, a large sunken garden and several pavilions and buildings,
many of which remain to be excavated. It is clear, however, that the wealth of
local rulers was based on the control of the ancient trade route and on gold
mining. A huge landslide has landed rotary stone querns, used for the milling
of gold containing quartz, at the riverbank of the Panj.
The palace, on the
highest point of the site, overlooks a large valley with several constructions,
among them a sunken garden, a pavilion, a graveyard, a wine press and a large
open space, referred to as the polo field. The “Sunken Garden” is a deepened
area of 50 by 90 meter with three descending terraces and a rectangular area,
possibly a pond, accessible from a staircase along the eastern side. The
retaining walls are strengthened with half-columns. Karon’s Sunken Garden is
one of the many garden complexes that were created in this part of Central Asia
under the Shaybanid dynasty (1428-1598 AD) and that are known to have been
inspirational to Muhammad Zahir al-Din Babur (1526-1530 AD), the first Mughal emperor.
The use of terraces, ponds and retaining walls with half-columns resembles
Bagh-e Babur near Kabul
The “Polo Field” is a large area with a terraced
embankment on one side and a large dry stone wall along the other, and has the
approximate size of a modern polo field, hence its name. In a large complex
such as Karon, a Maidan, a large open area where various activities could take
place, is a feature that is to be expected.
In between the “Sunken Garden” and the “Polo
Field” lies a square pavilion, possibly a mausoleum, built in dry stone
technique combined with bricks for the curvature of the arches. The monument is
still under investigation but it is clear that it has known many building
phases. Several overlapping platforms are present at its base and at some
point, the building was encased in walls with half-columns, much like those of
the Sunken Garden, that completely closed the access to the building. A 6th-7th
century coin found in the upper part of the pavilion is the only find at
present and suggests the core of the building may predate the Shaybanid era. Its
central position in the valley emphasizes its importance.
Karon: the central pavilion.
gold mining activities
The Belgian team set out to investigate the
gold mining activities and survey the
area. A large number of rotary quern stones are present amidst landslide debris
along the right bank of the Panj river, just below the mountaintop site of
Karon. These were mostly lower quern stones but also some upper mill stones and
two upper mill stones which had been in the process of being extracted. Their
present location and their position (many are tilted or even upside down) is
not their original place of use. They have been moved, most probably by a
landslide but recent roadworks involving rock blasting may also have had an
Rotary quern stones nr. 6 and 7 (top) and upper mill stones 25 and 26 during
the extraction (bottom)
Contrary to the exploitation of alluvial gold from the river,
which is a relatively simple technique (panning or washing out), the use of
quern stones indicates the more complicated exploitation of gold containing
quartz veins. This requires a large skilled labour force and a central power
that organises and oversees the complex workflow of mining, ore reduction and
smelting. The technology is documented in Egypt and consists of the following
1. 1. The ore
mining : the veins of gold containing quartz can be mined in open areas or by
following the veins in underground tunnels
(often open fire is used to break down the quartz veins to workable
2. 2. The quartz
ore had to be crushed and milled to obtain a powdery material that could be
further concentrated by washing. Large blocks were crushed with hand hammers or
pestles on dimple stones; the smaller particles were then milled in rotary
querns to a fine substance.
3. 3. Smelting of
the ore (on-site or in a specialised refinery) followed by “gold from lead
separation” techniques. These chemical processes involved heavy metals which
may have impacted on the environment and involved individuals.
The geological and
archaeological survey was directed at locating possible mining and industrial
areas. Iron smelting activities are attested in rooms near the mountaintop
palace, which is considered to be the local seat of power. The presence of
Chinese export porcelain and painted muqarnas dates this palace to the
15th-16th century. Possibly the smelting and refining activities took place in
this area, where excavations are ongoing. The geological survey was based on a
petrological analysis whereby in-situ rocks were described and sampled for
further chemical, mineralogical and petrological research. On the field 5 rock
units were observed: (1) fylite (high diagenetic equivalent of mudstone), (2)
fylite with quartz veins, (3) shists (medium diagenetic equivalent of
mudstone), (4) granite-granodiorite and (5) granodiorite intruded with quartz
veins. The shists may be reformed to saprolite by chemical and fysical
weathering of this rock-type and in some zone’s well-formed pyrite crystals up
to 1 cm3 occur.
There were no archaeological
traces of the mined quartz veins, possibly they were located in the landslide
area to the west of the mountaintop palace. Any open mining activities in the saddle
areas between the mountaintops, may be hidden by recent erosive depositions.
and impact of gold mining activities on humans
The sunken garden in
front of the mountaintop palace was studied and sampled to establish its use
and flora. This was done by digging a pedological window of 1 m3 in the square lowest area of the garden (though
to be possibly a pool) and describing the sedimentological and pedological features.
Samples now need to be processed.
location of the graveyard and
view of tombs 1 to 5
graveyard on the slope descending from the mountaintop palace towards the
sunken garden was partly excavated. A row of 8 cist tombs was discovered. The
tombs were constructed on the natural bedrock, the long sides with shist
stones, the front and top with large slabs. The tombs were protected upslope by
a low dry stone wall, in front of the tombs was a narrow paved path. The
downslope short side of several tombs was destroyed by erosion. One of the
tombs had been re-used and contained two skeletons. The individual had been
killed by two cuts in the head, one of which had removed part of the skull. The
second skeleton was only partially preserved. Since the graveyard belonged to
the Islamic era, the skeletal remains were reburied. However, biological
samples were collected from five tombs. They will be tested for the presence of
heavy metals as possible side-effect from ore refining activities and analysed
with regard to nutrition. Carbon 14 dating on the different individuals will
provide a time range for activities at Karon.
