Pyramids of Egypt - From Cabillia's Researches, as re-corded in Belzoni's Narrative.
"The enterprise of Captain Cabillia was hazardous and bold, and nothing but an enthusiasm for discovery could induce a man to take such a step. The consul, with Mr. Briggs, Mr. Beechey, and myself, went to see the operations that were going on. Captain Cabillia's circumstances were much better than mine; but he had no superfluous wealth at command, to continue what he had begun, which required a supply beyond his means. Mr. Briggs was the first who generously offered to furnish money for this purpose; and, after a consultation with Mr. Salt, they agreed to support the work to any extent that might be required. This gentleman not only encouraged the undertaking at the pyramid, but has exerted his influence with Mohammed Ali, for the general advantage of the commerce of Europe.

The Pyramids Of Egypt
"The enterprise of Captain Cabillia is worthy the attention of every one interested in antiquities, as he had solved a question by which the learned world has been puzzled for many centuries. The famous well, which has given rise to so much conjecture, turns out to be a communication with a lower passage, leading into an inferior chamber, discovered and opened by himself. He first descended the well to the depth of thirty-eight feet, where his progress was stopped by four large stones. Three of these being removed, there was space enough for a man to pass through; but the fourth he could not stir, though he had the help of Mr. Kabitsch, a young man in the employment of Mr. Baghos, who bore a share of the expense with the captain. Twenty-one feet below this place they found a grotto, seventeen feet long and four high; and seven feet below this, a platform, from which the well descended two hundred feet lower. The captain went down, and at the bottom found earth and sand; but from the hollow sound under his feet, he judged that the passage must communicate with some other apartment below. He then set some Arabs at work to remove the sand; but the heat was so great, and the candles so incapable of burning, for want of oxygen, that they were compelled to desist. The captain then turned his researches to another quarter, and began to enlarge the entrance into the first passage of the pyramid. For this operation he was well rewarded; for by it he found that the passage continued downward, and having employed several men, and taken out a great deal of earth and rubbish, at last, after a long and ardent toil, he came in contact with the bottom of the well, where he found the baskets and rope which had been left there. The same day that this occurred, was that on which we had agreed to visit the pyramids, and I had the pleasure to be an eye-witness of the arduous task of Captain Cabillia. Proceeding in his laborious researches, he found that the passage led into a chamber cut out of the rock, under the centre of the pyramid.
"Captain Cabillia made several researches round the pyramids also, but none exceeded his toil in uncovering the temple sphinx. He found a small temple between the two paws, and a large tablet of granite on its breast. The tablet is adorned with several figures and hieroglyphics, and two representations of sphinxes are sculptured on it. Before the entrance into the small temple was a lion, placed as if to guard the approach. Farther on from the front of the sphinx, is a staircase of thirty-two steps, at the bottom of which is an altar, with a Greek inscription, of the time of the Ptolemies. At each side of the altar was a sphinx of calcareous stone, much mutilated. From the base of the temple to the summit of the head, is sixty-five feet; the legs of the sphinx are fifty-seven feet long, from the breast to the extremity of the paws, which are eight feet high. Forty-five feet from the first altar, he found another, with an inscription, alluding to the emperor Septimus Severus; and near to the first step was a stone, with another Greek inscription, alluding to Antoninus.
"Notwithstanding his own occupation about the sphinx, Captain Cabillia employed other people to carry on researches. He opened some of the mausoleums which were choked up with sand, and found several small chambers, with hieroglyphics and figures, some of them pretty well executed, and in good preservation. In one of the pits he found some mummies, in their linen envelopes, and various fragments of Egyptian antiquity. He also opened some of the smaller pyramids, and from the suggestion of Mr. Brings to follow a certain direction, he succeeded in finding the entrance into one of them; but it appears, that it was so decayed in the interior, he could advance only a few feet. No doubt this led into some chamber or apartment, containing perhaps a sarco phagus, & c."
