Osireion, just to the north of the temple of Seti. Ahmose II in the Twenty-sixth Dynasty rebuilt the temple again, and placed in it a large monolith shrine of red granite, finely wrought. The foundations of the successive temples were comprised within approximately . depth of the ruins discovered in modern times; these needed the closest examination to discriminate the various buildings, and were recorded by more than 4,000 measurements and 1,000 levellings. The last building added was a new temple of Nectanebo I, built in the Thirtieth Dynasty. From the Ptolemaic times of the Greek occupancy of Egypt, that began three hundred years before the Roman occupancy that followed, the structures began to decay and no later works are known. Cult centre From earliest times, Abydos was a cult centre, first of the local deity, Khentiamentiu, and from the end of the Old Kingdom, the rising cult of Osiris. A tradition developed that the Early Dynastic cemetery was the burial place of Osiris and the tomb of Djer was reinterpreted as that of Osiris. Decorations in tombs throughout Egypt, such as the one displayed to the right, record pilgrimages to Abydos by wealthy families. Great Osiris Temple From the First Dynasty to the Twenty-sixth Dynasty, nine or ten temples were successively built on one site at Abydos. The first was an enclosure, about , enclosed by a thin wall of unbaked bricks. Incorporating one wall of this first structure, the second temple of about square was built with walls about thick. An outer temenos (enclosure) wall surrounded the grounds. This outer wall was made wider some time around the Second or Third Dynasty. The old temple entirely vanished in the Fourth Dynasty, and a smaller building was erected behind it, enclosing a wide hearth of black ashes. Pottery models of offerings are found in these ashes and were probably the substitutes for live sacrifices decreed by Khufu (or Cheops) in his temple reforms. At an undetermined date, a great clearance of temple offerings had been made and the modern discovery of a chamber into which they were gathered yielded the fine ivory carvings and the glazed figures and tiles that demonstrate the splendid work of the First Dynasty. A vase of Menes with purple hieroglyphs inlaid into a green glaze and tiles with relief figures are the most important pieces found. The Khufu Statuette in ivory, found in the
