Archaeology of Igbo-Ukwu

Peter Garlake compares the Igbo-Ukwu bronzes "to the finest jewelry of rococo Europe or of Carl Faberge," and William Buller Fagg states they were created with "a strange rococo almost Faberge type virtuosity". Frank Willett says that the Igbo-Ukwu bronzes portray a standard that is comparable to that established by Benvenuto Cellini five hundred years later in Europe. Denis Williams calls them "an exquisite explosion without antecedent or issue". One of the objects found, a water pot set in a mesh of simulated rope is described by Hugh Honour and John Fleming as The high technical proficiency and lack of known prototypes of the Igbo-Ukwu bronzes led to initial speculation in the academic community that they must have been created after European contact and phantom voyagers were postulated. However research and isotope analysis has established that the source of the metals is of local origin and radio carbon dating has confirmed a 9th-century date, long before the earliest contact with Europe. The Igbo-Ukwu artifacts did away with the hitherto existing colonial era opinions in archeological circles that such magnificent works of art and technical proficiency could only originate in areas with contact to Europe, or that they could not be crafted in an acephalous or egalitarian society such as that of the Igbo. Archaeological sites containing iron smelting furnaces and slag have been excavated dating to 2000 BC in Lejja and 750 BC in Opi, both in the Nsukka region about 100 kilometers east of Igbo-Ukwu. == Discovery ==

The initial finds were made by Isaiah Anozie while digging in his compound in 1938. In 1946, he handed over the artifacts to the Nigerian Department of Antiquities. Other bronze artifacts found in Anozie's compound were collected by Surveyor of Antiquities Kenneth Murray in 1954. Following a 2014 memorial for Shaw, Igwe of Igbo-Ukwu Martin E. Ezeh granted permission for new fieldwork at Igbo-Ukwu. New plans for exploration of the site were coordinated by Shaw's wife, Pamela Jane Smith Shaw, in 2019 and 2021. Fieldwork on this project aimed at expanding the temporal and spatial record of the ancient settlement. Archaeologists further excavated Igbo Richard, Igbo Isaiah, and Igbo Jonah, discovering an assemblage of large ceramic pottery and evidence of cultural deposits. == Overview of Site Layout and Findings ==

The Igbo-Ukwu site is located approximately 366 meters above sea level on a ridge Nanka sands of the Ameki formation characterized by an uneven topography of sandstones and ironstones; the area is mostly deprived of groundwater and surrounded by the Aghomili River in the east and the Obizi River in the west. Bronze, copper and glass artifacts at Igbo Isaiah lay below a compound wall which had to be removed before the excavation. Additionally, there are features (likely tree stumps) filled with small pieces of pottery. The Igbo Richard site contained human remains from several individuals, beaded wristlets and anklets, and a wooden stool which has been associated with a single set of human skeletal remains (possibly belonging to a priest-king). The Igbo Jonah site (which produced the least amount of associated archaeological material) produced a significant example of ritual pottery, as well as charcoal, animals bones, and some bronze sculptures. Further excavations in 2019 and 2021 to the west of Igbo Richard yielded deposits of pottery, bronze, copper, iron objects and slags, chalk, bone, and palm kernel. ==Chronology==

The first radiocarbon dates from Igbo-Ukwu were published by Shaw in 1970 and gave a range of 1075–1110 BP, with a standard error of ±100 and ±150 years, dating the site to the 9th century. This 10th century dating was further backed by Mcintosh et al.’s study of textiles published in the same year. The new radiocarbon dates open "the possibility that some or all of the Igbo Isaiah bronzes and beads are somewhat younger than previously believed, but certainly pre-date European coastal contact by several centuries. Mcintosh et al. however, state that "These dates do not...narrow the date range for the Igbo Richard burial, or illuminate the key question of its temporal relationship to Igbo Isaiah and Igbo Jonah."...there has been a tendency in the literature to regard the three sites as contemporaneous. However, the new dates reported by Daraojimba et al...suggest that Igbo-Ukwu may have been in use for several centuries. == Textiles ==

Significant findings have been made in the last 50 years at the Igbo-Ukwu site, especially in textiles. Samples from the British Museum have allowed for new studies of Igbo-Ukwu fabrics, including a scanning electron microscopy analysis of two fabric samples. This study found that the samples, which were uncovered in 1938 at the Igbo Isaiah compound, were woven with yarn that was 0.3-0.4mm in diameter and weave densities of both 24 warp and 16 weft/cm. These findings follow earlier studies by the Shirley Institute of samples found at the same site, provided by Charles Thurstan Shaw. The textile samples recovered by Shaw in 1960 (the whereabouts of which are currently unknown) and those recovered by Isaiah Anozie in 1938 (which belong to the British Museum and are the subject of new analyses) were primarily found to be of two distinct fiber types: bast and leaf/grass. Bast fibers were overwhelmingly attributed to Ficus trees, and leaf/grass fibers were chiefly attributed to Raphia palms. The use of these fibers represents an old weaving tradition from the forest zone of Nigeria, and these materials have almost entirely been replaced by cotton and wool today. These textiles have been speculated to hold religious or spiritual significance, but ethnographic and archaeological evidence is sparse in regard to the meaning of forest zone textiles and tree bast fibers. Therefore, the spiritual significance of these textiles remains speculative.   Accelerator mass spectrometry (AMS) dating was performed on one textile sample from Igbo Isaiah, placing the date of textile creation in the 1200-1300s CE. This is the first direct date obtained for an artifact from Igbo Isaiah, and it contrasts with the ninth-century CE date previously offered by Shaw on the basis of less precise radiocarbon results and stylistic seriation performed on pottery and bronzes from Igbo-Ukwu. == Beads ==

Over 165,000 glass and carnelian beads were found at Igbo-Ukwu; the quantity of beads contributes to the site's uniqueness in Western African archaeology. Archaeologists are able to use the morphology and chemical composition of the beads as insight into Igbo-Ukwu participation in long-distance trade networks and a general chronology of interaction. A recent analysis of 138 beads, selected for a range of different types and colors, showed that the most common type of bead analyzed was the soda-lime glass bead produced using plant ash. These were likely made from glass produced in Mesopotamia and eastern regions of Iran, and likely moved along the eastern Niger corridor route by the ninth or tenth centuries. However, several other glass bead chemical compositions have not been traced to a source, such as glass composed of soda-aluminum and soda-lime fluxed with a mineral alkali. Less analysis has been performed for the carnelian beads and Susan McIntosh argues that more research is needed into the possibility of any Saharan trade connections. == Metallurgy ==

(Lagos) The metal workers of ancient Igbo-Ukwu were not aware of commonly used techniques such as wire making, soldering or riveting which suggests an independent development and long isolation of their metal working tradition. It is therefore perplexing that they were able to create objects with such fine surface detail that they depict, for example small insects which seem to have landed on the surface. Though these appear to have been riveted or soldered on to the artifacts, they were actually cast in one piece. However the complexity of some of the Igbo-Ukwu objects has led to considerable altercation between various metallurgic experts and debates regarding the actual production process which is an affidavit for the highly developed and intricate work of the ancient artists. The composition of the metal alloys used in the production of the bronze is unique, with an unusually high silver content and is distinct from alloys used in Europe, the Mediterranean or other African bronze centers. About 85-90% of the metal ore used to produce the bronze originated from old mines in Abakiliki about 100 kilometers from Igbo-Ukwu. This finding is corroborated by recent lead isotope and silver content analysis of fragmented metal objects. A small percentage of ores are thought to have originated from a secondary source. However, an exact location has not been confirmed. Potential sources include North African countries like Tunisia and Morocco, per lead isotope analyses of copper-tin alloys. ==Gallery==
