19th century. 18 ¼” length, finely forged with offset section leaf shaped point. Alternating forged and bright polished surfaces. Cylindrical bolster and opened seam conical socket. As with most Congolese tribes, the Mangbetu were slavers in East African trade which supplied the Arab countries, South America and the flesh market. That last, flesh for human consumption, had largely been ignored but for a few accounts like Glave. Recent anthropological studies assisted by the wealth of information compiled on the internet document attribute a much greater proportion of the slave harvest to the cannibalism market. The Mangbetu specifically, are noted to be cannibals during the period.
