Radiocarbon Dating in Archaeology: Triangulation and Traceability

When radiocarbon dating techniques were applied to archaeological material in the 1950s they were hailed as a revolution. At last archaeologists could construct absolute chronologies anchored in temporal data backed by immutable laws of physics. This would make it possible to mobilize archaeological data across regions and time-periods on a global scale, rendering obsolete the local and relative chronologies on which archaeologists had long relied. As profound as the impact of 14C dating has been, it has had a long and tortuous history now described as proceeding through three revolutions, each of which addresses distinct challenges of capturing, processing and packaging radiogenic data for use in resolving chronological puzzles with which archaeologists has long wrestled. In practice, mobilizing radiogenic data for archaeological use is a hard-won achievement; it involves multiple transformations that, at each step of the way, depend upon a diverse array of technical expertise and background knowledge. I focus on strategies of triangulation and traceability that establish the integrity of these data and their relevance as anchors for evidential reasoning in archaeology

Scottish historical archaeology: international agendas and local politics

Historical archaeology as practiced in Scotland is divergent from the mainstream tradition of historical archaeology/post-medieval archaeology that dominates North America and the English-speaking world. Cultural and historical forces have shaped an historical archaeology with a deeper time depth, which extends back into the Middle Ages. It also focuses on different subjects reflecting the political concerns associated with Scottish national identity. Examples drawn from Glasgow’s history are used to illustrate the distinctiveness of the Scottish tradition and how it is evolving. I argue that one of its strengths of Scottish historical archaeology is that it provides a corrective contrast to the subjects and approaches which dominate historical archaeology in the English-speaking world
