A unique and well-preserved mosaic depicting the battle of David and Goliath has been looted in Syria. I was first shown a higher-res version of this image several months ago, but was not allowed to share it. It’s now posted on a French website, and you can read a (poor) Google translation with this link. At this point, there do not appear to be any other stories on the discovery, but perhaps that will change.
An official in the Directorate General of Antiquities and Museums in Syria believes that the mosaic comes from a church in northern Syria and dates to about AD 600. This may be the only known depiction of David and Goliath on a mosaic floor. The image depicts the warrior Goliath standing on the right side with full battle armor. To the left stands David with Goliath’s head on the end of his spear with the headless Goliath now laying at his feet. In the upper right corner, Saul and two others (brothers?) are depicted within the walls of a fortress. In the upper left corner are three women, probably those who rejoiced in David’s victory.
A Google search for this image reveals that it was posted on several Arabic websites on July 21-22, 2014.
The Met has an image of a silver plate depicting the battle, dating to approximately the same time (AD 630).
