Excavations along the banks of the Sangha River have yielded a rare pair of palm-fiber sandals reinforced with decorative copper threading, dating to the Early Iron Age. Unlike utilitarian footwear, these sandals feature exaggerated soles and geometric patterns symbolizing the flow of water, indicating they were intended for ceremonial use by a high-ranking individual during ritual processions.
The sandals were found at a site traditionally associated with ancient 'river-crossing' festivals, where communities celebrated the arrival of trade flotillas and seasonal migration. This discovery highlights the early sophistication of metal-weaving technologies in Central Africa and provides a tangible link to the ritual history of the Congo's riverine civilizations.
