When working on a dig site, you look at time periods two different ways-who was living in the location at the time and how advanced their technology was. In Ashkelon, we are looking at the people (Philistine, Roman, Byzantine), but also more broad time periods of the Bronze Age and the Iron Age. One way that archaeologists are able to determine these time periods is by looking at the pottery in the grid and what is in the clay. Check out one of our grid supervisors, Dr. Kate Birney, explain how this pottery is different, and visit our module to get more information about these time periods.
