Louise has brought to my attention a new article of hers that was just published that deals with the issue of how to define a transition between culture, periods, etc.
In particular, she discusses the LB/Iron Age transition in the eastern Mediterranean, with emphasis on issues relating to the Philistines.
The full title is:
Hitchcock, L. A. 2016. “What Does a Transition Mean?,” in P. Armstrong and J. Emerling (eds) Festschrift for Donald Preziosi. Journal of Art Historiography 15 (2016) 1-6.
Check it out – very nice!
