Gordon Govier has selected the top ten discoveries for Christianity Today, putting at the head of the list: (1) Herod’s Gate at Herodium; (2) Khirbet Summeily bullae; (3) Sheshonq’s scarab.
Robin Ngo has compiled an unranked list of the top ten for the Biblical Archaeology Society.
Looking the lists over, I would conclude that if you’re into spectacular discoveries, this wasn’t your year. If you include the broader world of archaeology, you fare better with the excavation of the Amphipolis tomb.
