As European merchants shifted their attention to Africa’s Atlantic coast in the late 15th century, the direction of the gold trade also shifted. In response, new states arose in Africa’s Akan-speaking regions, and aspects of the Saharan gold trade were transferred to this new market. For instance, the Akan system for weighing gold was based on the mithqal, a unit of weight equal to 4.5 grams (0.16 ounce). The Akan gold economy gave rise to an array of striking new objects for measuring gold: scoops, spoons, boxes, and especially copper-alloy weights in a great variety of forms, some of which also reference the geometric designs of the Muslim Saharan world.
