Outside this entrance the next king, Amen-hotep II (XVIII 7) added two small chambers (I H), which were again so constructed that their western side formed a front to the temple. He also presented _menats_ and vases to the sanctuary. Later rulers built additional chambers, pushing the temple front out further west. These chambers measured about 6 by 10 ft. each, with a seat on either side, and they eventually extended in one long line from the pylon along the whole length of the temenos, a distance of about 200 feet. They had been built under shelter of a break in the hill and were roofed over. Loose stones were piled up against their walls from outside along the whole length, which concealed them from view and gave them a subterranean character. Their purpose is a matter of conjecture. Probably they housed the guardians of the sanctuary, and served as an adytum to the cave of Hathor. The worshipper who approached the sanctuary from the west, and entered the outermost chamber, would feel himself in proximity to the cave while he was in reality a long way off. As the treasures which were stored in the cave multiplied, the device would help to ensure their safety. The erection of these buildings across the bed of wood-ashes put an end to the use of this space as a High Place of Burning. The site for offering the holocaust was therefore removed, probably to a site on the north side of the temple which had been squared in the course of quarrying stone for temple buildings. Corn was growing on this site in the winter of 1906, which prevented its being dug down to the rock. But the peculiar fertility of the accumulated soil which rendered the growing of corn possible, suggested that, here also, there might be an accumulation of wood ashes due to extensive burning. His successor, Tahutmes IV (XVIII 8), further extended the mines of the Twelfth Dynasty, and recorded his doing so by a tablet which is dated to the fourth year of his reign. Tablets of the fifth and the eighth years of his reign have also been mentioned by travellers, but these were sought for in vain in the winter of 1906. The next Pharaoh, Amen-hotep III (XVIII 9), also added further chambers to the temple approach (G F), and flanked the new entrance with two steles which record mining expeditions of his 36th year.
