¹⁰¹ Ife glass beads recovered from the ground were mentioned already by Merensky, , ‘Ueber die alten Schmuckkorallen der afrikanischen Völker’, Zeitschrift für Ethnologie (Verhandlungen), 14 (1882), 544Google Scholar. Almost a hundred years after this intelligent article the contemporary published accounts of the Ife glass industry (see for example Garlake, P. S., ‘Excavations at Obalara's Land, Ife: an interim report’, West African Journal of Archaeology, 4 (1974), 139Google Scholar: Shaw, , Nigeria, 146–7Google Scholar) must necessarily appear rather unintelligent: no chemical analyses (in the first item) and no photographs (in the second). More than twenty-five years after ‘extensive exploration…carried out in the grove of Olokon, where quantities of glass crucibles and glass beads were found over a very wide area’ (Fagg, B. E. B., ‘Some archaeological problems at Ife’ in Conférence Internationale des Africanistes de l'Ouest. V^e réunion Abidjan 1953, Compte rendu, 125–6Google Scholar) one would normally expect some more tangible results. In view of this archeological silence it is rather irritating to read that an Ife ‘ornament made of ground red and blue glass and set in thin copper mount…may prove of considerable interest’ (Ibid.). Also, it appears now that Ife was not the only place in Nigeria where glass was produced locally, perhaps already before our millennium (see Hartle, Donald D. ‘Preliminary report of the university of lbadan's Kainji rescue archaeology project, 1968A’, The West African Archaeological Newsletter, 12 (1970), 15–18)Google Scholar
