Haitian stone workshops stayed in use for six centuries

Radiocarbon dates from stratum IV at the flaked-stone workshop sites in Haiti come out between roughly 1 BCE and 625 CE. The material at these places is blade tools of high quality stone, and blades of that kind are usually taken as the signature of the earliest people to settle the island. The late dates put the two readings in conflict. Either the tool type is a poor marker of first arrival, or the sites went on being worked for many centuries after the first arrival, or both. Keegan and Hofman use the case to show how weak tool typology is as a clock. What the dates do establish is that people kept coming back to the same outcrops for six hundred years, because the stone there was worth the journey. That is detailed regional knowledge, held and handed on across generations, about where the good raw material lies on an island whose history most books only begin to describe in 1492.

The Council of Nicaea met in 325 CE to settle what Christians were required to believe about the nature of Christ. The argument was carried by Alexander, the Egyptian patriarch of Alexandria, and by his student Athanasius, who between them defeated the position that Christ was a created being. Out of the council came the doctrine of the Trinity and the statement of belief still recited as the Nicene Creed. Every later century of Christian theology in Europe was built on that foundation, and it was fixed in place by two men from Egypt. The other decisive figure of the period was also African. Augustine was born in the fourth century at Hippo, in what is now Algeria, of Amazigh descent, and his writing on sin, grace, predestination and the standing of the church shaped Catholic doctrine for sixteen hundred years and handed the Protestant reformers their arguments as well. He learned his trade inside an African intellectual tradition that had already produced Tertullian and Cyprian.

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.

The El Convento site on the northern coast of Puerto Rico has produced the earliest radiocarbon assay for the Huecoid, one of the two ceramic traditions present at the opening of the Ceramic Age in the region. The date is a problem for the accepted model, which has these groups moving slowly from east to west along the island's north coast. At Maisabel the sequence points the same way. Huecoid ceramics were found in a sealed layer directly beneath deposits of the Hacienda Grande style, which is Saladoid. Sealed stratification is the strongest evidence archaeology offers, because a layer under an undisturbed layer is older and no argument changes that. Together the two sites suggest the Huecoid were established in parts of Puerto Rico earlier than at eastern sites such as La Hueca, where the tradition was first defined. Migration maps for the first pottery-making societies of the Caribbean are being redrawn around dates like these.
