More recently, historians have been much less keen to define the Renaissance as a historical age, or even a coherent cultural movement. Randolph Starn, Historian at the University of California Berkeley, stated: "Rather than a period with definitive beginnings and endings and consistent content in between, the Renaissance can be (and occasionally has been) seen as a movement of practices and ideas to which specific groups and identifiable persons variously responded in different times and places. It would be in this sense a network of diverse, sometimes converging, sometimes conflicting cultures, not a single, time-bound culture".[13]
