  1. Mysteries of the Past

  2. The Great Pyramid of Giza

  3. Location of Giza Plateau

  4. Pyramid Complex in Giza • The Great Pyramid (Khufu), 3 pyramids for wives • Pyramid of Khafre, builder of the Sphinx • Pyramid of Menkaure

  5. The Great Sphinx

  6. Mystery of the location • the center of gravity of the continents • the exact center of all the land area of the world, dividing the earth's land mass into approximately equal quarters.

  7. The Great Pyramids v.s. The Belts of Orions

  8. The Great Pyramid • The only remaining seven wonders of the world • Visible from the moon • Built during the reign of Khufu, 2,720-2,560 BC • Estimated work force: 100,000 workers • Construction time: 20 years

  9. Great Pyramid: Work of Art • The Construction of the Pyramid: • Core stone : 2,300,000 blocks, 2~4 tons each • Casing stones: 144,000 mantle slabs, 15 tons each, transported from 14km away on the other side of the Nile • Stones in King’s Chamber: 60~80 tons, transported from 800 km away in Aswan • Total weight: 6.5 million tons.

  10. Interior Plan of the Pyramid • King’s Chamber: two airshafts pointing to the star Thuban, and Alnitak, in the Orion constellation • Queen’s chamber: two airshafts points to stars as well • Underground Chamber: 90 ft below ground level

  11. Great Pyramid: Amazing Accuracy • 4 sides (230.4 m) of the base with a mean error of only 58mm in length • 1 minute in angle from a perfect square • A horizontal base (53,000 m2) within 15mm discripency • 4 sides aligned to the four cardinal compass points, based on true north (rather than magnetic north) • Height : Base= 1: 2 x Pi

  12. The Great Pyramid Geometry

  13. Great Pyramid: Amazing Accuracy • Casing stones were cut to true plane with only 0.5mm error. • Casing stones were fitted together so perfectly that the tip of a knife cannot be inserted between the joints.

  14. The original entrance( higher one) vs the intrusive entrance (lower one, 820 AD)

  15. Extremely straight passage The longest descending passage (107 m long, 6mm in deviation) The shortest (15m, 0.5mm in deviation)

  16. Stonehenge

  17. Location • the English country of Wiltshire, in the Salisbury Plain

  18. Arial view of Stonehenge

  19. Construction Phases • 3100BC: Circular ditch and bank, 56 Aubrey holes • 2600BC: 43 bluestones (4 tons, from the Preselli Range 250km away), the Heelstone, the Slaughter Stone, 4 Station Stones

  20. 2450-2100BC: • 30 upright sarsen stones (26tons, over 10 feet tall), 30 lintels on top(6tons) • 5 trilithons (50 tons) in a horseshoe shape

  21. Myths and Legends –

  22. The Heel Stone

  23. The Heelstone • “Friar’s Heel” or the “Sunday Stone” • According to a folk tale in the 17 century: The Devil bought the stones from a woman in Ireland, wrapped them up, and brought them to Salisbury Plain. One of the stones fell into the Avon, the rest were carried to the plain. The Devil then cried out, “No-one will ever find out how these stones came here!” A friar replied, “That’s what you think!,”whereupon the Devil threw one of the stones at him and struck him on the heel. The stone stuck in the ground and is still there

  28. Sun rise v.s. Heel stone

  29. The Truth • Who built Stonehenge? • Ancient Englishmen during the late Stone Age to the Bronze Age (rather than the common-believed Celtic Priest, the Druids) • How to transport the stones? • On land: using wooden sledge, grease • On sea: log boats • How to erect the stones? • The ramp and leverage

  30. Easter Island

  31. Location • Found by the Dutch explorer Jacob Reggeveen, on Easter Sunday, 1772 • 3,600 km west of Chile and 2,075 km east of Pitcairn -- a completely islolated island

  32. Moai facing inland, seeming to protect the island

  33. Moai • Carved out of the volcanic crater Rano Raraku, using stone hand tools • mostly identical, some with hats • 887 stone statues • a quarter installed on ahu platforms • half remaining in Rano Raraku • the rest lie elsewhere on the island • Currently standing statues: 50 in total

  34. Moai with long ears, round eyes, and a hat

  35. Moai carved out of volcanic rocks

  36. Ahu: stone platforms for Moai to be erected on

  37. Precision: Stone wall behind the Ahu

  38. Easter Island in the Past • Once a lush island with giant palm trees, rich soil, and a good climate. • Original settlers arrived in canoes, 300-400AD • Polynesians first settled the island, around 1200AD, • a complex civilization flourished, producing bananas, potatoes, and sugar cane • Legend has it that • long-eared men introduced the stone carving technology and enslaved the local Polynesians

  39. Decline of An Ancient Civilization(17~18 century) • Overpopulation • Construction of Moais for ancestral worship • Deforestation • The extinction of large palms • Soil erosion • Drop in the quantities of fish and seabird • famine • Cannibalism Slavery in the 19 century A series of epidemics wiped out the remaing population
