Jerusalem's Temple Zero Underground

More than 500 years before King David Temple Zero, in Ancient Jerusalem's City of David had been constructed, used regularly and completely buried by falling groundcover. Whether King David ever re-discovered Temple Zero, or King Uzziah or Hezekiah were the first to re-discover it is debated here. Recently excavated elements, located on east and west adjacencies of Temple Zero, under virgin soil, in an ash layer above bedrock and a defensive wall prove the hypothesis that King David never discovered it. The discovery presents Temple Zero as a legitimate contender for the altar of the future temple in Jerusalem.

  

Seeds of wheat and barley, in a delicate 2m long, 1cm thick layer of ash, 5cm above bedrock, lay undisturbed from Middle Bronze Age through the Iron Age period of King David until King Uzziah and remained in place until their recent extraction. This delicate ash layer was preserved only because soft dirt had accumulated above it. In the ash, one seed was preserved under the wall of a late Iron Age building the other under collapsed rocks from surrounding Iron Age constructions. These seeds were carbon dated ~3290 years before the present (using 1950 as the reference age) and corelated to Middle Bronze Age archaeology of 1605-1510 BCE.

Iron Age wall constructors would first probe soft dirt until they discovered underlying bedrock sufficient to support wall construction. Then, they would remove soil and other moveable elements until they located the full length of bedrock necessary to support the wall width and length. On that they built their wall.

The Iron Age buildings were constructed after the wall, along Temple Zero's westernmost edge of Area U (map below) on the elevated edge of its rock-cut-rooms. The bedrock edge drops down the sheer east facing walls, of hollowed bedrock rooms 1.5-2m to the bedrock floor of the Temple Zero complex. Well before the Iron Age, the hollowed out rooms had once been filled with accumulated sand or natural dirt, that fell down the slope burying Temple Zero to a depth of  at least 1.5-2m.

Less than 10 meters east, further down slope toward the valley, additional evidence was found, between bedrock and leveling rocks supporting a Middle Bronze Age wall (red dots on the image above-right). This indicates earth below the supporting rocks of the walls base had been used 150-200 years before the seeds trapped in the ash layer (further to the west). However, around 1m above the bedrock additional evidence, taken from the walls' mortar, revealed entrapped seeds of a similar date as the ash layer seeds. Therefore, the walls foundation layers were constructed on a base above bedrock more than 150 years earlier, shown in the image below.

Curiously the study identified an unusual 17th century gap in evidence, indicating that the entire area went out of use during the 50-75 years that preceded the ash layer seeds and the building of this small Middle Bronze Age wall.  

This evidence at the rock-cut-rooms of Temple Zero strongly points to a natural burial, by slippage, wash, wind and accumulation. It is widely known to archaeologists that a location on a steep slope, such as this site, on the east of Mount Moriah would naturally accumulate sufficient dirt to be entirely covered over within 5 years. Complete burial would naturally obfuscate the existence of Temple Zero's rock-cut-rooms.

Since Temple Zero was buried underground sometime in the 17th century it would not have been used for active worship during the 10th century reign of King David because the evidence in the drainage channel was undisturbed. The next time all of Temple Zero's rock-cut-rooms were exposed was during the bedrock discovery phase, required for construction of Jerusalem's massive eastern defensive wall, in the 8th century leading up to or during the reign of King Uzziah. Almost 1000 years after the seeds became trapped in the ash layer, constructors of the massive defensive wall discovered, preserved and re-buried Temple Zero where it remained for another 2600 years until it was recently discovered in 2011.

The implications of this study are important because they provide a credible reason why Temple Zero was never discovered by King David and how the fragile matzevah (Stone of Israel), located in Temple Zero survived in its original place, preserved in soft sand, in tact all these years. One can only imagine what King Uzziah’s Iron Age wall constructors must have thought when they discovered and preserved it for our generation?
