Igbo-Ukwu Textiles: AMS Dating and Fiber Analysis

Abstract

Thurstan Shaw’s excavations at Igbo-Ukwu revealed many artifacts and technologies that remain astonishing, unique, and incompletely understood, both within Africa and more broadly, even after 50 years. Among these are the textiles recovered primarily from Igbo Isaiah, where fragments were preserved by contact with the bronze artifacts gathered in what has been interpreted as a shrine. In the 1960s, an analysis of 20 textile samples was unable to identify the plant fibers used to weave the fabric. In this article, we report the results of new fiber identifications based on the SEM study of two Igbo-Ukwu fabric samples curated by the British Museum. The combination of bast fibers from one or more species of the fig tree (Ficus genus) and leaf fibers from Raphia sp. provides evidence of a complex indigenous weaving technology that has largely disappeared from Africa. An AMS date on one of the samples provides an important new element to our understanding of the culture and chronology of Igbo-Ukwu. A final section positions the Igbo-Ukwu cloth within the known history of textiles in Africa, emphasizing sub-Saharan West Africa over the past two millennia.
