The smaller of the two is dedicated to the goddess Athor, the Venus of the Egyptians. The exterior is ornamented with six statues of deities recessed in the rock, each measuring thirty-five feet in height. In the interior there is a first hall, supported by square pillars, opening into a corridor, flanked by smaller halls, leading to the sanctuary. The front of the Great temple is adorned with four statues of the king seated upon his throne, each sixty feet high. In the great hall there are eight Osiride pillars, upward of thirty feet in height. The sides of the speos are carved with bass-reliefs, representing the conquests of Rameses the Great. There are some sixteen smaller chambers, the suite terminating in the sanctuary, which contains an altar and four statues—the three deities, Amun re, Phre, and Phtah, with the king seated in their company. Under the headings tombs and temples are comprised the chief architectural works of the Egyptians. Besides these there were one or two gigantic constructions, famous in antiquity, but which have now almost disappeared. Of these, the Labyrinth and the Lake Moeris were the most important. The former appears to have been an immense structure, half palace, half tomb, built by Amenemha III., of the twelfth dynasty. It was built on three sides of an open square, measuring about five hundred feet on the side, consisting of numerous chambers and courts, in two stories, one above and the other below the level of the ground. At the open end was placed a large pyramid, of which the ruins still remain. Herodotus admired the Labyrinth more than any other of the Egyptian buildings, declaring it to surpass the pyramids in labour and expense. Near by was the artificial Lake Moeris, formed to retain the Nile waters during the inundation, for the purpose of irrigating the country surrounding Memphis, during the dry season. It covered an immense area; tradition says 450 miles in circumference. The banks were fortified with massive masonry, and the waters distributed by means of locks and sluices.
