The History
The ancient site of Igbo Ukwu is situated in the modern day homelands
of Igbo peoples of southern Nigeria. Archaeological finds were first
discovered at this site in 1939 when an Igbo farmer named Isaiah Anozie
chanced upon several bronze objects as he was digging a cistern to
hold water in the dry season. It was not until 1959 that the archaeologist
Thurstan Shaw excavated this site and discovered that it must have
been part of a storehouse for ritual objects (Shaw 1977). Dated to
the 9th or 10th century A.D., Igbo Ukwu represents one of the earliest
examples of bronze casting in sub-Saharan Africa.
It is believed that the Igbo originated in an area about 100 miles
north of their current location at the confluence of the Niger and
Benue Rivers. They share linguistic ties with their neighbors the
Bini, Igala, Yoruba, and Idoma, with the split between them probably
occurring between five and six thousand years ago. The first Igbo
in the region may have moved onto the Awka-Orlu plateau between four
and five thousand years ago, before the emergence of sedentary agricultural
practices. As this early group expanded, so too did the Igbo kingdom.
The earliest surviving Igbo art forms are from the 10th century (Igbo
Ukwu), and the fine quality of those copper alloy castings suggest
that Igbo society had already achieved a level of technology rivaling
contemporary Europeans.
Archeological Relevance
It is possible that the inhabitants of Igbo-Ukwu had a metalworking
art that flourished as early as the ninth century (though this date
remains controversial). Three sites have been excavated, revealing
hundreds of ritual vessels and regalia castings of bronze or leaded
bronze that are among the most inventive and technically accomplished
bronzes ever made. The people of Igbo-Ukwu, ancestors of present-day
Igbo, were the earliest smithers of copper and its alloys in West
Africa, working the metal through hammering, bending, twisting, and
incising. They are likely among the earliest groups of West Africans
to employ the lost-wax casting techniques in the production of bronze
sculptures. Oddly, evidence suggests that their metalworking repertory
was limited and Igbo smiths were not familiar with techniques such
as raising, soldering, riveting, and wire making, though these techniques
were used elsewhere on the continent.
Regardless, the talent of these casters was truly astonishing.
Many of the castings were made in stages. For instance, in one bronze
bowl set on a flat stand found at Igbo-Ukwu, small decorative items
including insects and spirals were cast first and placed in the
wax model before the main parts of the bowl were made. The vessel
itself was then cast in two parts and fitted together by casting
a middle band. In addition to a variety of ritual vessels (whose
designs appear to reproduce the form of gourd vessels to which metal
handles have been attached), many other bronze items have been found
at Igbo-Ukwu, including pendants, crowns and breastplates, staff
ornaments, swords, and fly-whisk handles. These works were also
found with tens of thousands of beads, attained through trade for
slaves, ivory, or spices. Igbo-Ukwu bronzeworking was an isolated
phenomenon at the time, but bronze casting developed several centuries
later in other parts of Nigeria.
