Napata read Amun as one more face of a single Divinity

The peoples of the Napatan and Meroitic heartland followed a religion that recognised one Divinity, able to appear as individually named spirits. That shapes how their kings dealt with Egypt. When Napatan rulers gave recognition to Amun, Isis and Osiris, they most probably took those figures as further manifestations of the Divinity they already knew, absorbing them into a framework they had brought with them. A century of scholarship read the same acts as submission, as Kushite kings adopting the gods of a superior civilisation. Ehret reconstructs the Nilo-Saharan religion of Divinity back to the ninth millennium BCE, which puts it thousands of years ahead of the Egyptian cults in question. On that reconstruction the traffic runs the other way. Egyptian deities were taken into an older African theology and given a place inside it. Honouring Amun at Karnak becomes an act of interpretation performed by conquerors on the religion of the conquered.

Excavations at the Corinthia III site in Cuba turned up some of the earliest known Archaic Age pottery in the Caribbean. The find matters because the standard scheme awards pottery to the Ceramic Age migrations that arrived later out of South America, with Archaic peoples cast as foragers who did without it. The Cuban vessels show people working clay well before those migrations reached the island, alongside a move towards more settled living in the Late Archaic. Keegan and Hofman use the case against the period boundaries themselves. Archaeological ages are labels applied afterwards by researchers dividing up a continuum, and the material keeps crossing the lines drawn for it. What the Corinthia III pottery records is a wide range of practice across the archipelago, with communities inventing and adopting at their own pace. The people of the islands were doing their own experimenting, on their own schedule, for centuries before anyone brought them anything.

Herodotus wrote down what Carthaginians told Greek listeners about a coast beyond the Straits of Gibraltar. The ships would land, the crews would set their wares out in a row along the shore and raise smoke. People living there came down when they saw it, left gold beside the goods and withdrew. The Carthaginians came ashore and looked. If the gold matched the value they took it and sailed; if it did not they went back aboard and waited while more was added. Neither side touched what the other had put down until the exchange was settled. The same silent barter appears in much later accounts of the gold trade in the West African interior. The metal most likely came from the alluvial fields of Galam and Bambuk on the upper Niger and Senegal. This is among the earliest written notices of West African gold reaching the outside world.

Words for iron and for the work of the forge spread eastward across central Africa until they stopped in the west of South Sudan, along what is now the Ethiopian border. They stopped because another body of ironworking terms was coming the other way, southward out of the northern Ethiopian highlands. The two met in eastern South Sudan around the middle of the first millennium BCE. Each set carries its own words for the furnace, the smith and the tools, and each traces back to a different chain of transmission, one African in origin and one reaching the highlands from the Middle East across the Red Sea. Had iron been born once in Anatolia and radiated outward from there, the vocabulary across this whole region would descend from a single root. Instead there are two lexical systems running into each other from opposite directions, thousands of kilometres from where either began. That meeting place is where the single origin theory stops working.
