Professor Erez Ben Yosef of Tel Aviv University heads the Timna Excavation in the Arava Valley. He speaks with Eve about one of the lesser known aspects of the field of archaeological dating; an interdisciplinary realm that includes measuring geomagnetic intensity over the ages. Studying fired materials from Israel, specifically the age of the monarchies of David and Solomon, has provided a wealth of information not available anywhere else on the globe. Iron Age spikes are not what you think. There’s still so much to be learned and Israeli archaeologists are at the top of the (not only slag) heap.
