An ancient cemetery was uncovered in the southern Shephelah recently. The tombs are “6,000 years old” which makes it from the Chalcolithic period (though the article doesn’t specifically say). It does say that “The find yielded a treasure trove of ancient artifacts, including pottery, statues and jewelry all in mint-condition….He added that the find was the biggest of its kind and was invaluable for historians to deepen their understanding of the period.” I call the Chalcolithic age one of “surprising sophistication,” and this hoard could be good. The article is very brief but for the rest, see Haaretz. The photo is of an ossuary (burial box) from the Chalcolithic period, discovered elsewhere.
Note: despite the name similarity, Kiriath Gath is not near ancient Gath; the name was given to it early in the 20th century when the location of Gath was believed to be further south. Kiriath Gath is closer to biblical Lachish.
