Excavations near the Gihon Spring in Jerusalem’s City of David have uncovered three strange V-shaped markings that have archaeologists completely stumped. The mysterious shapes, which each measure about 1.5 feet in length, are carved into the bedrock floor of a room that was in use, according to dated pottery sherds, until at least the late ninth century B.C.E. Unfortunately, the excavation has found few clues to indicate either the meaning or function of the carvings, while only one other example, discovered more than a century ago in a nearby underground channel that remains unexcavated, has ever been recorded in Jerusalem.
“The markings are very strange, and very intriguing. I’ve never seen anything like them,” said Eli Shukron, of the two directors of the ongoing excavation. Shukron speculates the markings may have helped support some kind of wooden structure within the room, although its equally possible they could have had some either ritual or purely mundane function.
