The vast Hydraulic Underground System which collected through an aqueduct the Etam spring waters for Purification Rites and provided the rain waters under pressure to cleanse the Courts of the Temple of Jerusalem has been faithfully preserved by the zealous Muslims, engraved in the bed rock of the Haram where the Dome of the Dock and Mosque Al-Aqsa have been erected (Esplanade of the Mosques).

This ancient Underground Hydraulic System has been measured in minute detail by the 19th century Archaeologists who were the only Scientists ever allowed (for a brief period of 40-50 years) to explore the rocky underground of the Haram.
But stuck as they were by the unshakeable Postulate equaling the site of the lost Temple of the Jews to the site of the Dome of the Rock, the 19th century Archaeologists considered out of hand that the gigantic deep cisterns they were exploring in the Haram rocky underground were just STATIC ‘big wells’ from which were drawn all the waters needed for the Cult in the Temple (situated 20 to 10 meters above these waters and more than 100 meters upstream !).

In fact, when carefully cross-examined, and when elevations above sea level of these giant cisterns (storing 50 millions of ever flowing waters, and all interconnected through underground channels) are precisely calculated, a DYNAMIC HYDRAULIC CONCEPT reveals itself in its grandiose Biblical Finality :

The underground Hydraulic System devised by the Jewish Priests and the Engineers of King Solomon was in fact a Dynamic Hydraulic System, installed in a series of very precise cascades, so as to gather all the stored rain waters in order to make each drop of them religiously validated by the flow from the Aqueduct bringing the Waters of the Etam Sources, and then to convey these living Waters downstream (of the Haram) towards the square platform (180 m x 180 m) of the lost Temple, where all these Waters endowed with the Purification Power could reappear and gush forth at the surface of the Sanctuary, in order :

-a to comply with the exacting Biblical prescriptions concerning the complex Rites of Purification by Living Spring Waters which had imperatively to circulate freely by gravitation in the Sanctuary without the use of any recipient, so as to supply, for example amongst others, the Upper Storey of the Parvah Chamber where had been installed the Mikweh (Basin for Purifications by immersion in spring running waters) of the High Priest upon whom depended the supreme Purification of all Israel sins ;

-b to be able to convey all the stored cleansing rain waters downstream through a very precise succession of underground cascades of giant Cisterns down to canals specifically devised (mechanical *karcher*) so that these cleansing waters under pressure could gush forth at will on the Temple platform in order to wash the court where thousands of bloody sacrifices were offered to God.

Testimonies of ancient Texts of faithful rabbinical memory and of extra-rabbinical observations, in a same unanimous manner, describe a Temple where living purification waters and cleansing waters were flowing freely and continuously.

In fact the Haram was the Jewish citadel which overlooked and protected the Temple : and in its rocky entrails a very complex Water Tower was continuously giving birth to the purifying living waters and the cleansing waters which flowed downstream to the surface of the very modest square platform (180 m x 180 m) on which stood the lost Temple :

When the Roman Emperor Hadrian crushed down, in 135, the last revolt of the Jews led by Bar Kokhba (who had tried to restore the Temple destroyed by the Roman Emperor Titus in 70) Jerusalem was voided of all its inhabitants (Jews and Judeo-Christians) and was then repopulated with new Pagan immigrants to colonise the City that became entirely and exclusively Roman, and was renamed Aelia Capitolina.
In order to ensure the success of a secret strategy, the object being to eliminate any new idea of revolt by the Jews and any idea of a Single God, the God-Roman Emperor Hadrian had decided to eradicate from the memory of men the real location of the Temple.
With this objective in view, Hadrian expulsed the Jews from Jerusalem with an Edict formally forbidding all Jews to never again approach the City under pain of instant death.
This Interdiction forbidding the Jews (and Judeo-Christians) to approach Jerusalem remained in force for about two centuries and its application was facilitated by the visual inspection of circumcision of any suspect.

After the destruction of the Temple by the Roman Emperor Titus in 70, the Herodian Esplanade of the Citadel which overlooked and protected the Temple had be turned into the Campus of the Roman occupying Legion (X Frentesis), and, later, after the conquest of Jerusalem by Caliph Omar in 638, it became the Haram of the Muslims.

Hadrian strategy was thus a complete success up to nowadays, as nobody never suspected that in the entrails of this Haram remained INTACT the archaeological undisputable proofs (engraved in the rock) that this ancient Jewish Citadel had also been the almighty purifying Water Tower of the lost Temple of Solomon, located forcibly downstream.

The Book On-line (Volume E) The Temple of Solomon could not stand on its Water Tower (300 pages in English and in French with underground maps) at the Web Site : www.jerusalem-4thtemple.org provides all the documentation of ancient texts and all the precise scientific data of the 19th century archaeologists, which make altogether gravitationally, hydraulically and religiously IMPOSSIBLE that the Temple of Jerusalem could have ever stood on the site of the Muslim Haram.

And with this Book On-Line, anyone can decipher the vanished reality of the Lost Temple… to be rebuilt now.
