The Diy-Gid-Biy (DGB) sites are archaeological sites located around the Mandara Mountains of northern Cameroon and Nigeria, overlooking the several kilometers long Shikewe watershed.^[1] These sites get their name Diy-Gid-Biy from the Mafa language, which can be translated as "place of chiefly residence." There are 16 of these DGB sites which date back to around the 15th century AD.^[2] While knowledge of these sites has existed for some time, only in 2001 archaeologists began to investigate the sites and their cultural heritage in relation to the region.^[2]

Archaeology

The site

The Diy-Gid-Biy sites are of varying sizes, with DGB-1 and 2 being the largest. They are spread out over approximately 25 km, although DGB-1 and 2 are only 100 meters apart and are sometimes referred to as the same site.^[3] The DGB sites are constructed in a system of terraces and platforms built using a dry stone architecture that doesn't appear in any other sites using local granite and rocks, with stairs and silos being placed throughout. After studying various sections of whole and collapsed walls, archaeologists discovered that the walls were not constructed with shaped square stones, but rather built using stones naturally lying around and carefully fitted together with smaller stones propping up and holding together the walls.^[1] Based on research done by archaeologists, the DGB sites were built in several phases by the original builders who created sever layers of terraces and expanded the sites. The sites were then abandoned by the builders, but some were later on modified by the Mafa who filled in some of the areas with rubble and repurposed the bricks for various reasons.^[4]

The DGB sites have drawn in archaeologists, not only because of their unique structure and build, but because throughout most of the Manda Mountains there appears little evidence of occupation older than two centuries, while the plains below the mountains have presented archaeologists with sites dating back approximately 2,500 years ago. In fact, the DGB sites are the only coherent sites that have been found in the Mandara Mountains dating back so far.^[3]

Through the use of radiocarbon dating, archaeologists have been able to determine that the majority of the 16 sites were first constructed in the 15th century, although the wide range of dates from the various stages of development had originally made it difficult to figure out the structures beginnings. DGB-1 is a unique anomaly though in that radiocarbon dating places that particular site's origins back farther to around 1250 AD. At this site there has also been evidence that a pre-DGB culture lived at this location before construction was started, but little is truly known about this earlier people.^[5]

Excavation and discovery

Although knowledge of the sites has existed for many years, true archaeological research only began in 2001 with the excavations of DGB-2 and 8 by Nicholas David.^[2] A number of artifacts have been found at the sites, with items such as various ceramics originating from the Mandara Mountain region. Other artifacts that have been found are unfamiliar iron objects, a ground greenstone axe, upper grindstones, quartz hammerstones, and grindstone-mortars. While most of the objects found originate back to a time before the Mafa lived in the region, archaeologists have noted that the ceramics that have been found are barely, if at all, different from modern Mafa pottery.^[1]

At DGB-1 though, while regional items such as pottery and stone tools were found, other artifacts such as copper and glass items that didn't originate from the area were discovered as well, thus indicating that the people of DGB-1 had contact with peoples of other areas, something that wasn't as evident through previously excavated artifacts. In fact, other archaeological excavations of the Mandara region have presented a lack of artifacts originating from outside the area, with DGB-1 being basically the only site to show evidence of contact with areas beyond the Mandara region.^[5]

Other artifacts that have been found at DGB-1 include iron spear tips and iron arrow heads found under the floor of the site, as well as an iron hoe and chain. These finds suggest that the inhabitant at one point smelted iron and forged their own tools, although it is unknown when these items were made. The make of the iron artifacts has also been compared to iron items made by the Mafa of today, which bear a likeness to the artifacts, even though the Mafa and the builders of the DGB sites are not one and the same.^[6]

Hypothesis of use

Based on the archaeology done around the sites, as well as traditions used by the modern Mafa of the region, experts believe that the DGB sites were constructed as ritual structures relating to rain and water. The DGB sites began to appear around the time that a severe drought was occurring in the region, and so the construction makes sense in regards to ritual practices of the Mafa today who inhabit the region. Archaeologists have also found a large amount of sand and gravel from a local river that had been brought to DGB-2 and 8, possibly as a physical representation of flowing water.^[5]

Several other suggestions as to the purpose of the DGB sites have also been given, especially in the description of the sites presented in the UNESCO World Heritage tentative list. These purposes include the sites being defensive forts or places of refuge in times of war, places of burial for local chiefs, locations of residence for the elites of the region, and/or market centers or places of trade.^[7] While some of these ideas at the moment lack evidence to back them up, the construction of the DGB sites with towers and walls has supported the idea of the locations being defensive structures, while the finding of artifacts that didn't originate from the region has also convinced others that at least DGB-1 may have had a purpose in regards to engaging with foreign peoples. These foreign artifacts have even led some archaeologists, such as Nicholas David, to the hypothesis that at least the DGB-1/2 sites acted as places of interchange with peoples to the north, possibly as a place of trade.^[8]

Possible interactions

A number of archaeologists have presented the concept that a great deal of the interactions that occurred with foreign peoples at DGB-1 seem to have happened around the same time that European and Arabic writers noted the rise of Wandala, otherwise known as the Mandara Kingdom. Thus experts believe that some sort of trade occurred between the two peoples, as well as there possibly being a relationship between the creation of the DGB sites and Wandala around the same time.^[3]

World Heritage Status

This site was added to the UNESCO World Heritage Tentative List on April 18, 2006 in the Cultural category and remains on the Tentative list today.^[7] Reasons for presence in the list include: because they provide a link between the past and present history of the Mandara region, they provide a unique archaeological perspective to the area as sites that stand on their own, and they are viewed by different native peoples as sacred ground which brings them closer to the spirits through the construction of many different alters constructed on or around the sites.^[2]

Flag Fen, east of Peterborough, England, is a Bronze Age site developed about 3500 years ago, consisting of more than 60,000 timbers arranged in five very long rows, creating a wooden causeway across the wet fenland. Part-way across the structure a small island was formed. Items associated with it have led scholars to conclude that the island was of religious significance. Archaeological work began in 1982 at the site, which is located 800 m east of Fengate. Flag Fen is now part of the Greater Fens Museum Partnership. A visitor centre has been constructed on site and some areas have been reconstructed, including a typical Iron Age roundhouse dwelling.

An artifact, or artefact, is a general term for an item made or given shape by humans, such as a tool or a work of art, especially an object of archaeological interest. In archaeology, the word has become a term of particular nuance and is defined as an object recovered by archaeological endeavor, which may be a cultural artifact having cultural interest.

The archaeology of Israel is the study of the archaeology of the present-day Israel, stretching from prehistory through three millennia of documented history. The ancient Land of Israel was a geographical bridge between the political and cultural centers of Mesopotamia and Egypt. Despite the importance of the country to three major religions, serious archaeological research only began in the 15th century. Although he never travelled to the Levant, or even left the Netherlands, the first major work on the antiquities of Israel is considered to be Adriaan Reland's Antiquitates Sacrae veterum Hebraeorum, published in 1708. Edward Robinson, an American theologian who visited the country in 1838, published its first topographical studies. Lady Hester Stanhope performed the first modern excavation at Ashkelon in 1815. A Frenchman, Louis Felicien de Saucy, embarked on early "modern" excavations in 1850. Today, in Israel, there are some 30,000 sites of antiquity, the vast majority of which have never been excavated.

The Mandara Mountains are a volcanic range extending about 190 km along the northern part of the Cameroon–Nigeria border, from the Benue River in the south to the north-west of Maroua in the north. The highest elevation is the summit of Mount Oupay, at 1,494 m (4,900 ft) above sea level.

Kapsiki (Ka-Tsepkye) is a people living on both sides of the border between North Cameroon and Northeast Nigeria. They are called Kapsiki in Cameroon, and Kamwe (Higi) in Nigeria. Together they amount to about 120,000 people. Their language, Psekiye or Kamwe, consists of eleven dialects including Nkafa, Sina, Ghye, Humsi, Dakwa and Tilli and belongs to the Chadic language family.

Kintampo complex is the period in prehistory that saw the transition to sedentism in West Africa, specifically in the Bono East region of Ghana and parts of eastern Côte d'Ivoire that began sometime between 2500-1400 BCE. Besides being a classic example of early forest dwellers in West Africa, Kintampo is significant because there is evidence of a drastic change in food production techniques due to the transition from nomadic hunter-gather lifestyles to life in stationary settlements. This change is known as sedentism and is typical of societies who have access to, or are developing systems of agriculture. Ceramic sculptures of humans and animals indicate that the Kintampo settlements were inhabited by practitioners of both pastoralism and horticulture.

Mumba Cave, located near the highly alkaline Lake Eyasi in Karatu District, Arusha Region, Tanzania. The cave is a rich archaeological site noted for deposits spanning the transition between the Middle Stone Age and Late Stone Age in Eastern Africa. The transitional nature of the site has been attributed to the large presence of its large assemblage of ostrich eggshell beads and more importantly, the abundance of microlith technology. Because these type artifacts were found within the site it has led archaeologists to believe that the site could provide insight into the origins of modern human behavior. The cave was originally tested by Ludwig Kohl-Larsen and his wife Margit in their 1934 to 1936 expedition. They found abundant artifacts, rock art, and burials. However, only brief descriptions of these findings were ever published. That being said, work of the Kohl-Larsens has been seen as very accomplished due to their attention to detail, especially when one considers that neither was versed in proper archaeological techniques at the time of excavation. The site has since been reexamined in an effort to reanalyze and complement the work that has already been done, but the ramifications of improper excavations of the past are still being felt today, specifically in the unreliable collection of C-14 data and confusing stratigraphy.

Poverty Point State Historic Site/Poverty Point National Monument is a prehistoric earthwork constructed by the Poverty Point culture. The Poverty Point site is located in present-day northeastern Louisiana though evidence of the Poverty Point culture extends throughout much of the Southeastern Woodlands.

Daima is a mound settlement located in Nigeria, near Lake Chad, and about 5 kilometers away from the Nigerian frontier with Cameroon. It was first excavated in 1965 by British archaeologist Graham Connah. Radiocarbon dating showed the occupations at Daima cover a period beginning early in the first millennium BC, and ending early in the second millennium AD. The Daima sequence then covers some 1800 years. Daima is a perfect example of an archaeological tell site, as Daima’s stratigraphy seems to be divided into three periods or phases which mark separate occupations. These phases are called Daima I, Daima II, and Daima III. Although these occupations differ from each other in multiple ways, they also have some shared aspects with one another. Daima I represents an occupation of a people without metalwork; Daima II is characterized by the first iron-using people of the site; and Daima III represents a rich society with a much more complex material culture.
