But the place where this method has been carried out with peculiarly ingenious skill is the necropolis at Mugheir. The top of the platform, in the body of which the tombs are sunk, is covered with a brick pavement laid with special care, in which every chink is filled up with bitumen. Under this upper crust the coffins are ranged in order, one above the other, each one being placed separately in a small chamber. At intervals brick tubes are met with, fitted into one another and forming a sort of immense flue hidden in the structure. The lower extremity of the pipes opened into a drain; the upper end, on a level with the surface of the pavement of the terrace, was furnished with a cap pierced with an infinite number of small holes like a skimmer. Through these the rain-water was carried off, and this system of drainage was so wonderfully well understood and carried out, that it has remained intact to our own day, and, according to Loftus, the tombs have been so well preserved that they are found perfectly dry, including the bodies and their furniture. We shall see the Assyrians take similar precautions to preserve the terraces of the Ninevite palaces from the percolation of water.
The construction of a temple or palace was the occasion of a religious ceremony analogous to that which we call the laying of the first stone. In a hollow formed in the foundation-wall a cylinder of baked clay was deposited ([fig. 8]), on which an inscription was written describing the erection of the building and setting forth the piety and great deeds of the prince; this cylinder was accompanied by various talismanic objects: cones and statuettes of bronze and baked clay, cylindrical seals, votive tablets, sometimes of silver or gold. Among the foundations of the palace of Gudea, M. de Sarzec found four of these cavities in the wall measuring 1 ft. 1 in. by 10 in. by 4 in.; they still contained the cylinders and amulets deposited there.
Hiding-places of the same kind have been observed at Senkereh, at Mugheir, and among the ruins of almost all the Chaldæan and Assyrian buildings. The Assyrians themselves, when they wished to restore an old ruined temple, took pains first to find out the hiding-place of the foundation-cylinder or timmennu.
The last king of Babylon, Nabonidus, relates in one of the official inscriptions of his reign how he happened to find the timmennu of the earliest builders of the temple of the Sun at Larsa. King Kurigalzu (about B.C. 1350), and later Esarhaddon (B.C. 680-667), and Nebuchadnezzar himself, had repaired this venerated sanctuary, and sought vainly for the hiding-place of the talismans. “Then I, Nabonidus, inspired by my piety towards the goddess Istar of Agade, my sovereign, caused an excavation to be made. The gods Samas and Rammanu granted me their constant favour, and I found the foundation-cylinder of the temple of E-Ulbar.” It bore the name of the king Sagasaltias (about b.c. 1500). After reading the inscription, Nabonidus restored it to its place and himself made another cylinder to record his researches and his own works; he deposited it in the foundation by the side of the ancient cylinder. Modern explorers, no doubt also favoured by Samas and Rammanu, found in a sufficiently good state of preservation the mysterious hiding-places and the precious objects which had been piously placed there 550 years before our era.[16]

II. Statues and Bas-reliefs.
The discoveries of M. de Sarzec at Tello, and those of other explorers in Chaldæa, allow us to go back almost to the origin of sculpture in Western Asia. Our museums possess, in fact, bas-reliefs and statues belonging to a rudimentary stage of art, the remote age of which is still attested by the archaic inscriptions which accompany them, and these most ancient
