As art objects circulate over time, they connect various people, places, times, stories, and even historiographies. Although they cannot speak to us directly about their biographies, we can still interrogate them and related evidence in order to learn more about who once possessed them and where and how they were kept. As we do this, we can draw on the concept of circulation to direct scholarly attention toward how not only objects but also knowledge about them moves. Objects, knowledge, and their significance for those involved is continuously circulated and negotiated, yielding new knowledge and meaning in the process. Thus, we might endeavor to elaborate both the spatial and temporal dimensions of provenance research as integral parts of contemporary art history.
